Every day, everyone who uses the internet uses the Domain Name System. The key to the domain name system lies in the highest level of the system, the top-level domains. These are the domains such as .com, .org, and .net. While you are probably very familiar with a few of these, there are actually a lot more. A whole lot more. A lucky few top-level domain name holders actually managed to hit the jackpot. Learn more about top-level domain names and how they are organized and distributed on this episode of Everything Everywhere Daily.

Was bedeutet eigentlich Domain Name System?
The Domain Name System, or DNS, is the backbone of the internet, translating human-readable domain names into numerical IP addresses that computers use to locate services and devices worldwide. Despite DNS's importance, it is susceptible to cyber attacks due to its weaknesses. The purpose of this article is to explain the fundamentals of DNS protocols. It will also go into detail about the most common DNS attacks, along with effective mitigation strategies. Overview of DNS Protocols DNS operates as a distributed database hierarchy organized into a tree-like structure. The key components of DNS include: View More: DNS Protocols and Attacks
In episode 188 of our SAP on Azure video podcast we talk about about DNS, Domain Name System. DNS acts like a phonebook to resolve IP addresses through their domain names. When something goes wrong, then often the whole network communication breaks down. It's always DNS! Who doesn't know this term whenever it comes to networking issues. In a lot of cases we see customers using Azure DNS Services in the context of hybrid networking with SAP scenarios -- both Azure native and RISE with SAP. Since this can become quite complicated, I am happy to have two experts with us today again: Evren and Konstantin. https://www.linkedin.com/feed/update/urn:li:activity:6841398577495977984/Find all the links mentioned here: https://www.saponazurepodcast.de/episode188Reach out to us for any feedback / questions:* Robert Boban: https://www.linkedin.com/in/rboban/* Goran Condric: https://www.linkedin.com/in/gorancondric/* Holger Bruchelt: https://www.linkedin.com/in/holger-bruchelt/ #Microsoft #SAP #Azure #SAPonAzure #DNS #Networking #RISEwithSAP
Behind almost every web page, email, and podcast is a system that translates addresses understandable to humans to something which can be understood by computers. The system is one of the foundations of the Internet, yet its origin was in a handmade list that was placed on a single computer. Unbeknownst to the creators of the system, it would eventually affect the fortunes of entire countries.

DNS, or Domain Name System, is the lookup system responsible for converting human-readable domain names like google.com into IP addresses, which is the format that computers need to communicate with each other. But in this process, a LOT of data is leaked about your internet activities, and collected by all kinds of entities like ISPs and government organizations.In this video, we'll explain how DNS works, and how to set up your DNS to make your internet browsing far more private.00:00 Intro00:37 What is DNS?01:09 How Does DNS Work?07:02 Privacy Concerns09:07 How to Protect DNS Queries10:14 Quad913:50 How to Switch to Quad915:33 ConclusionDNS privacy is a critical part of your home network security.

De Nederlandse overheid gebruikt (nog steeds) Facebook, maar de vraag is hoe lang nog. Want: een onderzoek naar privacy-risico's op dat platform heeft een boel rode vlaggen opgeleverd. Wat gaat hier precies mis? Dat vragen we aan Sjoera Nas, senior privacy adviseur bij Privacy Company, die dit onderzoek uitvoerde. Kan Videoland flink groeien als Disney+ en Netflix dat nauwelijks doen? De tijd van onbezorgdheid en gouden bergen bij streamingdiensten lijkt voorbij, want de groei is uit de streamingplatforms van Netflix en Disney. Wat betekent dat voor platforms uit Nederland, met als grootste speler RTL's Videoland? Daarover praten we met Arno Otto, in het verleden nauw betrokken bij de oprichting van RTL's streamingplatform en nu Chief Transformation Officer bij Talpa. Cyberveiliger met DNS Slimmer omgaan met het Domain Name System, oftewel DNS, zou een ‘easy win' kunnen zijn voor betere bescherming tegen cyberaanvallen. Maar hoe zou dat in zijn werk gaan? En is het überhaupt uitvoerbaar? Dat bespreken we met Steven van Gysel, Manager Solutions Architect Noord-Europa, bij security- en netwerk-bedrijf Infoblox. Meer podcasts over tech?

When we think about the components that go together to make the internet work we probably think of browsers and IP addresses but there is one critical component that brings it together - the Domain Name System or DNS. It's the reason behind when you type cnn.com you end up on the right website.The design of DNS is more than 30 years old, but still is a critical point of the internet today.In October 2021, a misconfiguration error caused Facebook to disappear from the internet for nearly 7 hours. To understand the notion of DNS better, we spoke with Michael Kaczmarek who is the former VP of Product Management at Neustar Security Solutions. Michael directed the research efforts into distributed denial of service attacks and DNS trends for Neustar working closely with the cross-functional team to publish insights on changes in the cybersecurity landscape.Prior to joining Neustar, Michael was with Verisign for more than 18 years where he served in various capacities including VP of product management and marketing.Prior to Verisign, he was a systems engineering manager for Lockheed Martin in charge of their Solid Rocket Motor Disposition in Russia Program.Michael is a Ponemon Fellow and holds a Bachelor of Science in aerospace engineering from the University of Maryland and a Master of Engineering in environmental engineering from Johns Hopkins University.In this wide-ranging discussion, we looked at How Distributed Denial of Service (DDoS) attacks are on the riseHow AI can be used to detect cyber threatsWhat the Internet 3.0 might look likeWhat the Facebook 2021 outage tells us about DNSWhat to look for in a DNS providerWhy every business owner should care about DNSThe top3 cybersecurity trendsNew threats such as API securityAnalysis of a real DNS hackWhy Cybersecurity needs to concern every boardThree top cybersecurity tipsIf you are truly digitally curious, then you will want to listen to this episode in full.More about MichaelLinkedInTwitterNeustar Security SolutionsYour Host: Actionable Futurist® Andrew GrillFor more on Andrew - what he speaks about and replays of recent talks, please visit ActionableFuturist.comfollow @AndrewGrill on Twitteror @andrew.grill on Instagram.

Around six hours after Facebook, WhatsApp and Instagram went down, service started coming back online. The reason for the outage was not immediately clear. However, multiple security experts quickly pointed to a Domain Name System problem as a possible culprit. To learn more about how CNN protects listener privacy, visit cnn.com/privacy
The Internet is not a simple story to tell. In fact, every sentence here is worthy of an episode if not a few. Many would claim the Internet began back in 1969 when the first node of the ARPAnet went online. That was the year we got the first color pictures of earthen from Apollo 10 and the year Nixon announced the US was leaving Vietnam. It was also the year of Stonewall, the moon landing, the Manson murders, and Woodstock. A lot was about to change. But maybe the story of the Internet starts before that, when the basic research to network computers began as a means of networking nuclear missile sites with fault-tolerant connections in the event of, well, nuclear war. Or the Internet began when a T3 backbone was built to host all the datas. Or the Internet began with the telegraph, when the first data was sent over electronic current. Or maybe the Internet began when the Chinese used fires to send messages across the Great Wall of China. Or maybe the Internet began when drums sent messages over long distances in ancient Africa, like early forms of packets flowing over Wi-Fi-esque sound waves. We need to make complex stories simpler in order to teach them, so if the first node of the ARPAnet in 1969 is where this journey should end, feel free to stop here. To dig in a little deeper, though, that ARPAnet was just one of many networks that would merge into an interconnected network of networks. We had dialup providers like CompuServe, America Online, and even The WELL. We had regional timesharing networks like the DTSS out of Dartmouth University and PLATO out of the University of Illinois, Champaign-Urbana. We had corporate time sharing networks and systems. Each competed or coexisted or took time from others or pushed more people to others through their evolutions. Many used their own custom protocols for connectivity. But most were walled gardens, unable to communicate with the others. So if the story is more complicated than that the ARPAnet was the ancestor to the Internet, why is that the story we hear? Let's start that journey with a memo that we did an episode on called “Memorandum For Members and Affiliates of the Intergalactic Computer Network” sent by JCR Licklider in 1963 and can be considered the allspark that lit the bonfire called The ARPANet. Which isn't exactly the Internet but isn't not. In that memo, Lick proposed a network of computers available to research scientists of the early 60s. Scientists from computing centers that would evolve into supercomputing centers and then a network open to the world, even our phones, televisions, and watches. It took a few years, but eventually ARPA brought in Larry Roberts, and by late 1968 ARPA awarded an RFQ to build a network to a company called Bolt Beranek and Newman (BBN) who would build Interface Message Processors, or IMPs. The IMPS were computers that connected a number of sites and routed traffic. The first IMP, which might be thought of more as a network interface card today, went online at UCLA in 1969 with additional sites coming on frequently over the next few years. That system would become ARPANET. The first node of ARPAnet went online at the University of California, Los Angeles (UCLA for short). It grew as leased lines and more IMPs became more available. As they grew, the early computer scientists realized that each site had different computers running various and random stacks of applications and different operating systems. So we needed to standardize certain aspects connectivity between different computers. Given that UCLA was the first site to come online, Steve Crocker from there began organizing notes about protocols and how systems connected with one another in what they called RFCs, or Request for Comments. That series of notes was then managed by a team that included Elizabeth (Jake) Feinler from Stanford once Doug Engelbart's project on the “Augmentation of Human Intellect” at Stanford Research Institute (SRI) became the second node to go online. SRI developed a Network Information Center, where Feinler maintained a list of host names (which evolved into the hosts file) and a list of address mappings which would later evolve into the functions of Internic which would be turned over to the US Department of Commerce when the number of devices connected to the Internet exploded. Feinler and Jon Postel from UCLA would maintain those though, until his death 28 years later and those RFCs include everything from opening terminal connections into machines to file sharing to addressing and now any place where the networking needs to become a standard. The development of many of those early protocols that made computers useful over a network were also being funded by ARPA. They funded a number of projects to build tools that enabled the sharing of data, like file sharing and some advancements were loosely connected by people just doing things to make them useful and so by 1971 we also had email. But all those protocols needed to flow over a common form of connectivity that was scalable. Leonard Kleinrock, Paul Baran, and Donald Davies were independently investigating packet switching and Roberts brought Kleinrock into the project as he was at UCLA. Bob Kahn entered the picture in 1972. He would team up with Vint Cerf from Stanford who came up with encapsulation and so they would define the protocol that underlies the Internet, TCP/IP. By 1974 Vint Cerf and Bob Kahn wrote RFC 675 where they coined the term internet as shorthand for internetwork. The number of RFCs was exploding as was the number of nodes. The University of California Santa Barbara then the University of Utah to connect Ivan Sutherland's work. The network was national when BBN connected to it in 1970. Now there were 13 IMPs and by 1971, 18, then 29 in 72 and 40 in 73. Once the need arose, Kleinrock would go on to work with Farouk Kamoun to develop the hierarchical routing theories in the late 70s. By 1976, ARPA became DARPA. The network grew to 213 hosts in 1981 and by 1982, TCP/IP became the standard for the US DOD and in 1983, ARPANET moved fully over to TCP/IP. And so TCP/IP, or Transport Control Protocol/Internet Protocol is the most dominant networking protocol on the planet. It was written to help improve performance on the ARPAnet with the ingenious idea to encapsulate traffic. But in the 80s, it was just for researchers still. That is, until NSFNet was launched by the National Science Foundation in 1986. And it was international, with the University College of London connecting in 1971, which would go on to inspire a British research network called JANET that built their own set of protocols called the Colored Book protocols. And the Norwegian Seismic Array connected over satellite in 1973. So networks were forming all over the place, often just time sharing networks where people dialed into a single computer. Another networking project going on at the time that was also getting funding from ARPA as well as the Air Force was PLATO. Out of the University of Illinois, was meant for teaching and began on a mainframe in 1960. But by the time ARPAnet was growing PLATO was on version IV and running on a CDC Cyber. The time sharing system hosted a number of courses, as they referred to programs. These included actual courseware, games, convent with audio and video, message boards, instant messaging, custom touch screen plasma displays, and the ability to dial into the system over lines, making the system another early network. In fact, there were multiple CDC Cybers that could communicate with one another. And many on ARPAnet also used PLATO, cross pollinating non-defense backed academia with a number of academic institutions. The defense backing couldn't last forever. The Mansfield Amendment in 1973 banned general research by defense agencies. This meant that ARPA funding started to dry up and the scientists working on those projects needed a new place to fund their playtime. Bob Taylor split to go work at Xerox, where he was able to pick the best of the scientists he'd helped fund at ARPA. He helped bring in people from Stanford Research Institute, where they had been working on the oNLineSystem, or NLS and people like Bob Metcalfe who brought us Ethernet and better collusion detection. Metcalfe would go on to found 3Com a great switch and network interface company during the rise of the Internet. But there were plenty of people who could see the productivity gains from ARPAnet and didn't want it to disappear. And the National Science Foundation (NSF) was flush with cash. And the ARPA crew was increasingly aware of non-defense oriented use of the system. So the NSF started up a little project called CSNET in 1981 so the growing number of supercomputers could be shared between all the research universities. It was free for universities that could get connected and from 1985 to 1993 NSFNET, surged from 2,000 users to 2,000,000 users. Paul Mockapetris made the Internet easier than when it was an academic-only network by developing the Domain Name System, or DNS, in 1983. That's how we can call up remote computers by names rather than IP addresses. And of course DNS was yet another of the protocols in Postel at UCLAs list of protocol standards, which by 1986 after the selection of TCP/IP for NSFnet, would become the standardization body known as the IETF, or Internet Engineering Task Force for short. Maintaining a set of protocols that all vendors needed to work with was one of the best growth hacks ever. No vendor could have kept up with demand with a 1,000x growth in such a small number of years. NSFNet started with six nodes in 1985, connected by LSI-11 Fuzzball routers and quickly outgrew that backbone. They put it out to bid and Merit Network won out in a partnership between MCI, the State of Michigan, and IBM. Merit had begun before the first ARPAnet connections went online as a collaborative effort by Michigan State University, Wayne State University, and the University of Michigan. They'd been connecting their own machines since 1971 and had implemented TCP/IP and bridged to ARPANET. The money was getting bigger, they got $39 million from NSF to build what would emerge as the commercial Internet. They launched in 1987 with 13 sites over 14 lines. By 1988 they'd gone nationwide going from a 56k backbone to a T1 and then 14 T1s. But the growth was too fast for even that. They re-engineered and by 1990 planned to add T3 lines running in parallel with the T1s for a time. By 1991 there were 16 backbones with traffic and users growing by an astounding 20% per month. Vint Cerf ended up at MCI where he helped lobby for the privatization of the internet and helped found the Internet Society in 1988. The lobby worked and led to the the Scientific and Advanced-Technology Act in 1992. Before that, use of NSFNET was supposed to be for research and now it could expand to non-research and education uses. This allowed NSF to bring on even more nodes. And so by 1993 it was clear that this was growing beyond what a governmental institution whose charge was science could justify as “research” for any longer. By 1994, Vent Cerf was designing the architecture and building the teams that would build the commercial internet backbone at MCI. And so NSFNET began the process of unloading the backbone and helped the world develop the commercial Internet by sprinkling a little money and know-how throughout the telecommunications industry, which was about to explode. NSFNET went offline in 1995 but by then there were networks in England, South Korea, Japan, Africa, and CERN was connected to NSFNET over TCP/IP. And Cisco was selling routers that would fuel an explosion internationally. There was a war of standards and yet over time we settled on TCP/IP as THE standard. And those were just some of the nets. The Internet is really not just NSFNET or ARPANET but a combination of a lot of nets. At the time there were a lot of time sharing computers that people could dial into and following the release of the Altair, there was a rapidly growing personal computer market with modems becoming more and more approachable towards the end of the 1970s. You see, we talked about these larger networks but not hardware. The first modulator demodulator, or modem, was the Bell 101 dataset, which had been invented all the way back in 1958, loosely based on a previous model developed to manage SAGE computers. But the transfer rate, or baud, had stopped being improved upon at 300 for almost 20 years and not much had changed. That is, until Hayes Hayes Microcomputer Products released a modem designed to run on the Altair 8800 S-100 bus in 1978. Personal computers could talk to one another. And one of those Altair owners was Ward Christensen met Randy Suess at the Chicago Area Computer Hobbyists' Exchange and the two of them had this weird idea. Have a computer host a bulletin board on one of their computers. People could dial into it and discuss their Altair computers when it snowed too much to meet in person for their club. They started writing a little code and before you know it we had a tool they called Computerized Bulletin Board System software, or CBBS. The software and more importantly, the idea of a BBS spread like wildfire right along with the Atari, TRS-80, Commodores and Apple computers that were igniting the personal computing revolution. The number of nodes grew and as people started playing games, the speed of those modems jumped up with the v.32 standard hitting 9600 baud in 84, and over 25k in the early 90s. By the early 1980s, we got Fidonet, which was a network of Bulletin Board Systems and by the early 90s we had 25,000 BBS's. And other nets had been on the rise. And these were commercial ventures. The largest of those dial-up providers was America Online, or AOL. AOL began in 1985 and like most of the other dial-up providers of the day were there to connect people to a computer they hosted, like a timesharing system, and give access to fun things. Games, news, stocks, movie reviews, chatting with your friends, etc. There was also CompuServe, The Well, PSINet, Netcom, Usenet, Alternate, and many others. Some started to communicate with one another with the rise of the Metropolitan Area Exchanges who got an NSF grant to establish switched ethernet exchanges and the Commercial Internet Exchange in 1991, established by PSINet, UUNet, and CERFnet out of California. Those slowly moved over to the Internet and even AOL got connected to the Internet in 1989 and thus the dial-up providers went from effectively being timesharing systems to Internet Service Providers as more and more people expanded their horizons away from the walled garden of the time sharing world and towards the Internet. The number of BBS systems started to wind down. All these IP addresses couldn't be managed easily and so IANA evolved out of being managed by contracts from research universities to DARPA and then to IANA as a part of ICANN and eventually the development of Regional Internet Registries so AFRINIC could serve Africa, ARIN could serve Antarctica, Canada, the Caribbean, and the US, APNIC could serve South, East, and Southeast Asia as well as Oceania LACNIC could serve Latin America and RIPE NCC could serve Europe, Central Asia, and West Asia. By the 90s the Cold War was winding down (temporarily at least) so they even added Russia to RIPE NCC. And so using tools like WinSOCK any old person could get on the Internet by dialing up. Modems for dial-ups transitioned to DSL and cable modems. We got the emergence of fiber with regional centers and even national FiOS connections. And because of all the hard work of all of these people and the money dumped into it by the various governments and research agencies, life is pretty darn good. When we think of the Internet today we think of this interconnected web of endpoints and content that is all available. Much of that was made possible by the development of the World Wide Web by Tim Berners-Lee in in 1991 at CERN, and Mosaic came out of the National Center for Supercomputing applications, or NCSA at the University of Illinois, quickly becoming the browser everyone wanted to use until Mark Andreeson left to form Netscape. Netscape's IPO is probably one of the most pivotal moments where investors from around the world realized that all of this research and tech was built on standards and while there were some patents, the standards were freely useable by anyone. Those standards let to an explosion of companies like Yahoo! from a couple of Stanford grad students and Amazon, started by a young hedge fund Vice President named Jeff Bezos who noticed all the money pouring into these companies and went off to do his own thing in 1994. The companies that arose to create and commercialize content and ideas to bring every industry online was ferocious. And there were the researchers still writing the standards and even commercial interests helping with that. And there were open source contributors who helped make some of those standards easier to implement by regular old humans. And tools for those who build tools. And from there the Internet became what we think of today. Quicker and quicker connections and more and more productivity gains, a better quality of life, better telemetry into all aspects of our lives and with the miniaturization of devices to support wearables that even extends to our bodies. Yet still sitting on the same fundamental building blocks as before. The IANA functions to manage IP addressing has moved to the private sector as have many an onramp to the Internet. Especially as internet access has become more ubiquitous and we are entering into the era of 5g connectivity. And it continues to evolve as we pivot due to new needs and threats a globally connected world represent. IPv6, various secure DNS options, options for spam and phishing, and dealing with the equality gaps surfaced by our new online world. We have disinformation so sometimes we might wonder what's real and what isn't. After all, any old person can create a web site that looks legit and put whatever they want on it. Who's to say what reality is other than what we want it to be. This was pretty much what Morpheus was offering with his choices of pills in the Matrix. But underneath it all, there's history. And it's a history as complicated as unraveling the meaning of an increasingly digital world. And it is wonderful and frightening and lovely and dangerous and true and false and destroying the world and saving the world all at the same time. This episode is pretty simplistic and many of the aspects we cover have entire episodes of the podcast dedicated to them. From the history of Amazon to Bob Taylor to AOL to the IETF to DNS and even Network Time Protocol. It's a story that leaves people out necessarily; otherwise scope creep would go all the way back to to include Volta and the constant electrical current humanity received with the battery. But hey, we also have an episode on that! And many an advance has plenty of books and scholarly works dedicated to it - all the way back to the first known computer (in the form of clockwork), the Antikythera Device out of Ancient Greece. Heck even Louis Gerschner deserves a mention for selling IBM's stake in all this to focus on things that kept the company going, not moonshots. But I'd like to dedicate this episode to everyone not mentioned due to trying to tell a story of emergent networks. Just because they were growing fast and our modern infrastructure was becoming more and more deterministic doesn't mean that whether it was writing a text editor or helping fund or pushing paper or writing specs or selling network services or getting zapped while trying to figure out how to move current that there aren't so, so, so many people that are a part of this story. Each with their own story to be told. As we round the corner into the third season of the podcast we'll start having more guests.

Your DNS server knows what websites you use, what the name of your mail server is, and which corporate services you use while working from your home office. And there are even broader challenges when it comes to protecting sensitive personal data in that context. Alexei Balaganski and Matthias continue their conversation about a fundamental Internet resource, the Domain Name System, this time walking the fine line between technology and trust.
The Domain Name System -- DNS -- is like the Internet's phone book. It's how computers match URLs to IP addresses in order to help you do things like look at web pages or send emails.Sure, the system seems like an obvious way of structuring the Internet now. After all, can you imagine the Web without Google.com and Amazon.com and Facebook.com? But the current structure of Internet domain names wasn't always an obvious solution to the problem.In this episode of Web Masters, you'll hear how the Domain Name System came into being from the man who invented DNS, Paul Mockapetris. Paul's vision for Internet routing was critical for making the Internet infinitely scalable. But, when he proposed it, he wasn't actually in a position to implement his vision. So, before his system could be adopted, he had to make sure nobody else's proposals were ever considered. Luckily, he was given a perfect opportunity to intervene.For a complete transcript of the episode, click here.

The security community generally agrees on the importance of encrypting private data: Add a passcode to your smartphone. Use a secure messaging app like Signal. Adopt HTTPS web encryption. But a new movement to encrypt a fundamental internet mechanism, promoted by browser heavyweights like Google Chrome and Mozilla's Firefox, has sparked a heated controversy. The changes center around the Domain Name System, a decentralized directory that acts essentially as the internet's address book.
Welcome to the History of Computing Podcast, where we explore the history of information technology. Because by understanding the past, we're able to be prepared for the innovations of the future! Todays episode is on the history of the Domain Name System, or DNS for short. You know when you go to www.google.com. Imagine if you had to go to 172.217.4.196, or the IP address, instead. DNS is the service that resolves that name to that IP address. Let's start this story back in 1966. The Beatles released Yellow Submarine. The Rolling Stones were all over the radio with Paint It Black. Indira Ghandi was elected the Prime Minister of India. US Planes were bombing Hanoi smack dab in the middle of the Vietnam War. The US and USSR agreed not to fill space with nukes. The Beach Boys had just released Good Vibrations. I certainly feel the good vibrations when I think that quietly, when no one was watching, the US created ARPANET, or the Advanced Research Projects Agency Network. ARPANET would evolve into the Internet as we know it today. As with many great innovations in technology, it took awhile to catch on. Late into the 1980s there were just over 300 computers on the Internet, most doing research. Sure, there were 254 to the 4th addresses that were just waiting to be used, but the idea of keeping the address of all 300 computers you wanted to talk to seemed cumbersome and it was slow to take hold. To get an address in the 70s you needed to contact Jon Postel at USC to get put on what was called the Assigned Numbers List. You could call or mail them. Stanford Research Institute (now called SRI) had a file they hosted called hosts.txt. This file mapped the name of one of these hosts on the network to a IP address, making a table of computer names and then IP addresses those matched with, or a table of hosts. Many computers still maintain this file. Elizabeth Feinler maintained this directory of systems. She would go on to lead and operate the Network Information Center, or NIC for short, for ARPANET and see the evolution to the Defense Data Network, or DDN for short and later the Internet. She wrote what was then called the Resource Handbook. By 1982, Ken Harrenstien and Vic White on Feinler's group at Stanford created a service called Whois, defined in RFC 812, which was an online directory. You can still use the whois command on Windows, Mac and Linux computers today. But by 1982 it was clear that the host table was getter's slower and harder to maintain as more systems were coming online. This meant more people to do that maintenance. But Postel from USC then started reviewing proposals for maintaining this thing, a task he handed off to Paul Mockapetris. That's when Mockapetris did something that he wasn't asked to do and created DNS. Mockapetris had been working on some ideas for filesystems at the time and jumped at the chance to apply those ideas to something different. So Jon Postel and Zaw-Sing Su helped him complete his thoughts which were published by the Internet Engineering Task Force, or IETF, in in RFC 882 for the concepts and facilities and RFC 883 for the implementation and specification in November 1983. You can google those and read them today. And most of it is still used. Here, he introduced the concept that a NAME of a TYPE points to an address, or RDATA and lives for a specified amount of time, or TTL short for Time To Live. He also mapped IP addresses to names in the specifications, creating PTR records. All names had a TLD or Top Level Domain name of ARPANET. Designing a protocol isn't the same thing as implementing a protocol. In 1984, four students from the University of California Berkeley wrote the first version of BIND, short for Berkeley Internet Name Domain, for BSD 4.3. Douglas Terry, Mark Painter, David Riggle, and Songnian Zhou using funds from a DARPA grant. In 1988 Paul Vixie from Digital Equipment Corporation then gave it a little update and maintained it until he founded the Internet Systems Consortium to take it over. BIND is still the primary distribution of DNS, although there are other distributions now. For example, Microsoft added DNS in 1995 with the release of NT 3.51. But back to the 80s real quick. In 1985, came the introduction of .mil, .gov, .edu, .org, .com TLDs. Remember John Postel from USC? He and Joyce K Reynolds started an organization called IANA to assign numbers for use on the Internet. DNS Servers are hierarchical, and so there's a set of root DNS servers, with a root zone controlled by the US Dept of Commerce. 10 of the 13 original servers were operated in the US and 3 outside, each assigned a letter of A through M. You can still ping a.root-servers.net. These host the root zone database from IANA and handle the hierarchy of the TLD they're authoritative for with additional servers hosted for .gov, .com, etc. There are now over 1,000 TLDs! And remember how USC was handling the addressing (which became IANA) and Stanford was handling the names? Well Feinler's group turned over naming to Network Solutions in 1991 and they handled it until 1998 when Postel died and ICANN was formed. ICANN or the Internet Corporation for Assigned Names and Numbers, merged the responsibilities under one umbrella. Each region of the world is allowed to manage their own IP addresses, and so ARIN was formed in 1998 to manage the distribution of IP addresses in America. The collaboration between Feinler and Postel fostered the innovations that would follow. They also didn't try to take everything on. Postel instigated TCP/IP and DNS. Postel co-wrote many of the RFCs that define the Internet and DNS to this day. And Feinler's showed great leadership in administering how much of that was implemented. One can only aspire to find such a collaboration in life and to do so with results like the Internet, worth tens of trillions of dollars, but more importantly has reshaped the world, disrupted practically every industry and touched the lives of nearly every human on earth.

Thanks to a push over the last few years, led by Google and others, encrypted HTTPS connections protect more data than ever as it passes between web servers and browsers. But another fundamental component of web browsing too often remains unencrypted: the Domain Name System connections that act as the address lookups of the internet. In Android 9, also known as Android Pie, Google has added a feature called Private DNS to start encrypting DNS on mobile.
