BGP in review for 2025

PING

In this episode of PING, APNIC Chief Scientist Geoff Huston returns with his annual review of BGP, reflecting on developments across 2025. Geoff has been publishing this year-in-review analysis of BGP dynamics for more than a decade, and this time he has uncovered some genuinely surprising shifts. His 2025 analysis has been published in two parts on the APNIC Blog. Border Gateway Protocol (BGP) is the mechanism by which network operators announce their Internet address space to the rest of the world and, in turn, learn about the addresses announced by others. Operators participating in the global default-free zone receive all publicly announced routes, each expressed as an IP prefix and associated with its originating Autonomous System Number (ASN). Every BGP speaker has a unique ASN, and all routing information is exchanged and interpreted through this fundamental identifier. In effect, the ASN is the basic unit of interdomain routing. BGP also carries path information that describes how routing announcements traverse the network. This data informs routing policy decisions — which paths to prefer, and through which commercial or technical relationships. While the protocol itself is well understood, the system as a whole is anything but simple. When more than 100,000 ASes are continuously exchanging routing information, complexity is unavoidable. Speaking BGP is about telling things and learning things, but it's also about deciding what to do with what has been learned. This is the work behind a router, and involves holding all the information and performing routing decisions on it, so the ‘size' of the information shared and learned has a direct impact on the ‘cost' of operating as a BGP speaker (cost here ultimately means memory and CPU). For most of the Internet's history, BGP growth has been relentless, forcing operators to continually ask whether their current routing infrastructure can accommodate future growth. All technology adoption has a life cycle, and is often referred to as the ‘technology adoption curve'. New technologies start out expensive and scarce, become cheaper and widely adopted, and eventually reach a point of saturation where growth slows and replacement becomes the dominant driver. For much of its existence, the Internet has remained firmly in the rapid growth phase of this curve, with sustained increases in users, networks, and routing information. Geoff has detected changes in the pace of growth for both IPv4 and IPv6, which suggest the underlying economics behind investment in Internet, and growth in customers has reached it's saturation point: We are entering a time where BGP growth may not have the same dynamics we've been used to, and questions about capital investment in BGP routing and underlying Internet Addressing are not the same.

NITK Students at IETF: Fresh Minds for standards development

PING

Play Episode Listen Later Jan 21, 2026 30:57

Welcome back to PING for 2026 and season 6. This time on PING, we have a pair of interviews with students from the National Institute of Technology Karnataka, Surathkal (NITK), recorded last year at IETF 122. This is the second time we've heard from students from NITK. We previously heard from Vanessa Fernandes and Kavya Bhat when they attended IETF 119 in 2024. NITK is a large, technically focused university located on India's south-western coast in the state of Karnataka. The state is home to major technology hubs, such as Bengaluru and Mangaluru, alongside institutions like NITK, which play a key role in developing technical talent. Against this backdrop, it is unsurprising that NITK students show a strong interest in network technologies and Internet protocol development. Dr Mohit Tahiliani, Associate Professor at NITK, has led a multi-year program involving undergraduate, postgraduate, and postdoctoral researchers to engage with emerging Internet standards. Through this program, participants explore new ideas, contribute code, and take part in IETF hackathons and Working Group activities. This work has been supported in part by the APNIC Foundation. Last time with Vanessa and Kavya, we explored NITK's multi-year campus IPv6 deployment, which has been underway for some time. That work has included direct engagement with the IETF, with Dr Mohit Tahiliani's students attending alongside Nalini Eklins, who is involved both in the IPv6 deployment at NITK and in IPv6 standards work within the IETF. Since then, both students have gone on to work in networking roles or to pursue further study, reflecting the longer-term impact of sustained involvement in operational and standards-based Internet engineering. This time, we've got two different projects and NINE students to hear from. The first group is Rati Preethi Subramanian, Shriya Anil, Mahati Kalale, Anuhya Murki and Supradha Bhat, who explored fair queuing disciplines, FQ_Codel, a derivative FQ_Codel++ and a new proposed model, FQ_Pie. They worked with the NS3 network simulator and CCPerf, exploring how these queueing disciplines compare, and discussed their project with me at IETF 122. The second group are Vartika T Rao, Hayyan Arshad, Siddharth Bhat and Bharadwaja Meherrushi Chittapragada, who looked at the YANG data model in the network management space, and more efficient ways to manage data coming out of networking systems using YANG. They wrote a producer-consumer model in Python code, and explored time-series databases using interface packet count collections as an example YANG dataset to explore, in the CBOR encoding. Finally, I spoke with Dr Mohit Tahiliani, who has been leading this project. He is strongly committed to bringing new and younger voices into IETF work, recognizing the value of exposing students to real-world protocol development early in their careers. This experience benefits participants by grounding their learning in practical standards work, while also helping the IETF engage with new contributors who may return to protocol development in the future. This sustained engagement has already had tangible outcomes: The students involved have gone on to roles in the ICT sector or to further academic study, demonstrating the long-term value of this collaborative model.

Crazy Wisdom

In this episode of the Crazy Wisdom Podcast, host Stewart Alsop sits down with Mike Bakon to explore the fascinating intersection of hardware hacking, blockchain technology, and decentralized systems. Their conversation spans from Mike's childhood fascination with taking apart electronics in 1980s Poland to his current work with ESP32 microcontrollers, LoRa mesh networks, and Cardano blockchain development. They discuss the technical differences between UTXO and account-based blockchains, the challenges of true decentralization versus hybrid systems, and how AI tools are changing the development landscape. Mike shares his vision for incentivizing mesh networks through blockchain technology and explains why he believes mass adoption of decentralized systems will come through abstraction rather than technical education. The discussion also touches on the potential for creating new internet infrastructure using ad hoc mesh networks and the importance of maintaining truly decentralized, permissionless systems in an increasingly surveilled world. You can find Mike in Twitter as @anothervariable.Check out this GPT we trained on the conversationTimestamps00:00 Introduction to Hardware and Early Experiences02:59 The Evolution of AI in Hardware Development05:56 Decentralization and Blockchain Technology09:02 Understanding UTXO vs Account-Based Blockchains11:59 Smart Contracts and Their Functionality14:58 The Importance of Decentralization in Blockchain17:59 The Process of Data Verification in Blockchain20:48 The Future of Blockchain and Its Applications34:38 Decentralization and Trustless Systems37:42 Mainstream Adoption of Blockchain39:58 The Role of Currency in Blockchain43:27 Interoperability vs Bridging in Blockchain47:27 Exploring Mesh Networks and LoRa Technology01:00:25 The Future of AI and DecentralizationKey Insights1. Hardware curiosity drives innovation from childhood - Mike's journey into hardware began as a child in 1980s Poland, where he would disassemble toys like battery-powered cars to understand how they worked. This natural curiosity about taking things apart and understanding their inner workings laid the foundation for his later expertise in microcontrollers like the ESP32 and his deep understanding of both hardware and software integration.2. AI as a research companion, not a replacement for coding - Mike uses AI and LLMs primarily as research tools and coding companions rather than letting them write entire applications. He finds them invaluable for getting quick answers to coding problems, analyzing Git repositories, and avoiding the need to search through Stack Overflow, but maintains anxiety when AI writes whole functions, preferring to understand and write his own code.3. Blockchain decentralization requires trustless consensus verification - The fundamental difference between blockchain databases and traditional databases lies in the consensus process that data must go through before being recorded. Unlike centralized systems where one entity controls data validation, blockchains require hundreds of nodes to verify each block through trustless consensus mechanisms, ensuring data integrity without relying on any single authority.4. UTXO vs account-based blockchains have fundamentally different architectures - Cardano uses an extended UTXO model (like Bitcoin but with smart contracts) where transactions consume existing UTXOs and create new ones, keeping the ledger lean. Ethereum uses account-based ledgers that store persistent state, leading to much larger data requirements over time and making it increasingly difficult for individuals to sync and maintain full nodes independently.5. True interoperability differs fundamentally from bridging - Real blockchain interoperability means being able to send assets directly between different blockchains (like sending ADA to a Bitcoin wallet) without intermediaries. This is possible between UTXO-based chains like Cardano and Bitcoin. Bridges, in contrast, require centralized entities to listen for transactions on one chain and trigger corresponding actions on another, introducing centralization risks.6. Mesh networks need economic incentives for sustainable infrastructure - While technologies like LoRa and Meshtastic enable impressive decentralized communication networks, the challenge lies in incentivizing people to maintain the hardware infrastructure. Mike sees potential in combining blockchain-based rewards (like earning ADA for running mesh network nodes) with existing decentralized communication protocols to create self-sustaining networks.7. Mass adoption comes through abstraction, not education - Rather than trying to educate everyone about blockchain technology, mass adoption will happen when developers can build applications on decentralized infrastructure that users interact with seamlessly, without needing to understand the underlying blockchain mechanics. Users should be able to benefit from decentralization through well-designed interfaces that abstract away the complexity of wallets, addresses, and consensus mechanisms.

professorjrod@gmail.comEver wonder how your phone grabs an IP address the instant you join Wi‑Fi? We break down the invisible handshake that makes it happen: DORA. From discovery to acknowledgement, we map each step of the DHCP exchange, explain lease timers, and show how networks hand out addresses at scale without stepping on their own toes. Along the way, we share practical stories from classrooms, offices, and coffee shops that turn abstract packets into clear mental models.We go deeper than definitions. You'll learn how scopes shape address pools, why reservations keep printers stable, and how APIPA exposes broken paths with 169.254.x.x clues. In segmented environments, relays and the GIADDR field become the traffic cops that steer requests to the right subnet; misconfigure them and clients get stranded. Security gets real too: rogue DHCP can poison DNS, starvation floods can exhaust pools, and well‑meaning mesh gear can become a second server. We detail protective moves like DHCP snooping, port security, and rate limiting, plus how snooping's binding tables feed stronger Layer 2 defenses.Resilience matters, so we unpack failover strategies—hot standby, load balancing, and legacy split scopes—and the rich set of DHCP options that deliver DNS, NTP, TFTP, and VoIP boot settings. We also tackle IPv6 with a sober lens: where SLAAC fits, when DHCPv6 is still essential, and why economics slow change even as IPv4 addresses remain scarce. If you support users, we hand you a troubleshooting playbook: spot APIPA, check relays, expand scopes, and use ipconfig release/renew to solve issues methodically and ace help desk interviews.If this helped you see the network with new eyes, tap follow, share with a teammate, and leave a quick review.

professorjrod@gmail.comEver wish the network would just explain itself? We walk through the real language of connectivity—how links come alive, how packets choose their paths, and how a few core ideas unlock routers, firewalls, addressing, and the exam questions that test them. It starts with the wire (and the air): DSL over copper, cable scaling with DOCSIS, fiber to an ONT at your home, and why fixed wireless, satellite, and 5G fill coverage gaps with very different tradeoffs in speed and latency. From there, we draw the line between moving traffic and governing it. Routers forward based on IP and subnets; firewalls enforce policy using IPs, protocols, and ports—think velvet rope, but for packets.We bring the TCP/IP stack down to earth with a clean mental model of layers and encapsulation, then dig into IPv4 addressing, subnet masks, and private ranges that rely on NAT to share a single public IP. You'll learn why static IPs belong on printers and servers, how DHCP's DORA flow keeps clients online, and what APIPA is telling you when a lease fails. We also size up IPv6—128-bit addresses, hexadecimal notation, dual stack—and unpack the practical roadblocks that slow adoption despite the promise of massive address space.Transport choices make or break performance, so we compare TCP's three‑way handshake and delivery guarantees with UDP's low-latency approach favored by streaming and gaming. We highlight the ports every tech should know—22, 53, 80, 443, 67/68, 21/20, 3389—because port literacy speeds troubleshooting. On identity and isolation, we translate DNS records (A, AAAA, CNAME, MX, TXT) into everyday use and show how VLANs reduce broadcast noise while VPNs protect data over untrusted networks. To cement it all, we run live quiz walkthroughs and model how to spot keywords, eliminate distractors, and reason under time pressure—skills you can carry straight into the CompTIA A+ and beyond.If this helped you think more clearly about networks, follow the show, leave a rating, and share it with a friend who's studying.

Sometimes weirdness occurs within DNS if you’re on an IPv4 network and you connect to a dual-stack or v6-only VPN. Maybe the browser doesn’t connect, but you can still send pings, or vice versa. Is the OS getting confused about which stack and which order of interfaces to request services? Is the weird behavior being... Read more »
