Let’s chat about point-to-point links. On today’s episode we cover what should and shouldn’t be done, and discuss why following RFC's doesn't always get you to the right place. We dig into questions including: Don't we just use link-local addresses for point-to-points? Shouldn't we assign a /127, just like we do a /31 in IPv4?... Read more »

Trends in the global BGP table--the Default Free Zone (DFZ) table--can tell us a lot about the state of the global Internet. Is the Internet growing? Is IPv6 growing, or are we still in a world of "all things IPv4?" Geoff Huston joins Tom Ammon and Russ White to review the state of the routing table from 2024.
In this episode, Job Snijders discusses RPKIViews, his long term project to collect the "views" of RPKI state every day, and maintain an archive of BGP route validation states. The project is named to reflect route views, the long-standing archive of BGP state maintained by the University of Oregon, which has been discussed on PING. Job is based in the Netherlands, and has worked in BGP routing for large international ISPs and content distribution networks as well as being a board member of the RIPE NCC. He is known for his work producing the Open-Source rpki-client RPKI Validator, implemented in C and distributed widely through the OpenBSD project. RPKI is the Resource PKI, Resource meaning the Internet Number Resources, the IPv4, IPv6 and Autonomous System (AS) numbers which are used to implement routing in the global internet. The PKI provides cryptographic proofs of delegation of these resources and allows the delegates to sign over their intentions originating specific prefixes in BGP, and the relationships between the AS which speak BGP to each other. Why rpkiviews? Job explains that there's a necessary conversation between people involved in the operational deployment of secure BGP, and the standards development and research community: How many of the worlds BGP routes are being protected? How many places are producing Route Origin Attestations (ROA) which are the primary cryptographic object used to perform Route Origin Validation (ROV) and how many objects are made? Whats the error rate in production, the rate of growth, a myriad of introspective "meta" questions need to be asked in deploying this kind of system at scale, and one of the best tools to use, is an archive of state, updated frequently, and as for route views collected from a diverse range of places worldwide, to understand the dynamics of the system. Job is using the archive to produce his annual "RPKI Year in review" report, which was published this year on the APNIC blog (it's posted to operations, research and standards development mailing lists and presented at conferences and meetings normally) and products are being used by the BGPAlerter service developed by Massimo Candela

In his regular monthly spot on PING, APNIC's Chief Scientist Geoff Huston discusses the slowdown in worldwide IPv6 uptake. Although within the Asia-Pacific footprint we have some truly remarkable national statistics, such as India which is now over 80% IPv6 enabled by APNIC Labs measurements, And Vietnam which is not far behind on 70% the problem is that worldwide, adjusted for population and considering levels of internet penetration in the developed economies, the pace of uptake overall has not improved and has been essentially linear since 2016. In some economies like the US, a natural peak of around 50% capability was reached in 2017 and since then uptake has been essentially flat: There is no sign of closure to a global deployment in the US, and many other economies. Geoff takes a high level view of the logisitic supply curve with the early adopters, early and late majority, and laggards, and sees no clear signal that there is a visible endpoint, where a transition to IPv6 will be "done". Instead we're facing a continual dual-stack operation of both IPv4 (increasingly behind Carrier Grade Nats (CGN) deployed inside the ISP) and IPv6. There are success stories in mobile (such as seen in India) and in broadband with central management of the customer router. But, it seems that with the shift in the criticality of routing and numbering to a more name-based steering mechanism and the continued rise of content distribution networks, the pace of IPv6 uptake worldwide has not followed the pattern we had planned for.

Welcome to episode 278 of The Cloud Pod, where the forecast is always cloudy! When Justin's away, the guys will… maybe get a show recorded? This week, we're talking OpenAI, another service scheduled for the grave over at AWS, saying goodbye to pesky IPv4 fees, Azure FXv2 VMs, Valkey 8.0 and so much more! Thanks for joining us, here in the cloud! Titles we almost went with this week: Another One Bites the Dust Peak AI reached: OpenAI Now Puts Print Statements in Code to Help You Debug A big thanks to this week's sponsor: Archera There are a lot of cloud cost management tools out there. But only Archera provides cloud commitment insurance. It sounds fancy but it’s really simple. Archera gives you the cost savings of a 1 or 3 year AWS Savings Plan with a commitment as short as 30 days. If you don’t use all the cloud resources you’ve committed to, they will literally put money back in your bank account to cover the difference. Other cost management tools may say they offer “commitment insurance”, but remember to ask: will you actually give me my money back? Archera will. Click this link to check them out AI Is Going Great – Or How ML Makes All It's Money 00:59 Introducing vision to the fine-tuning API. OpenAI has announced the integration of vision capabilities into its fine-tuning API, allowing developers to enhance the GPT-4o model to analyze and interpret images alongside text and audio inputs. This update broadens the scope of applications for AI, enabling more multimodal interactions. The fine-tuning API now supports image inputs, which means developers can train models to understand and generate content based on visual data in conjunction with text and audio. After October 31, 2024, training for fine-tuning will cost $25 per 1 million tokens, with inference priced at $3.75 per 1 million input tokens and $15 per 1 million output tokens. Images are tokenized based on size before pricing. The introduction of prompt caching and other efficiency measures could lower the operational costs for businesses deploying AI solutions. The API is also being enhanced to include features like epoch-based checkpoint creation, a comparative playground for model evaluation, and integration with third-party platforms like Weights and Biases for detailed fine-tuning data management. What does it mean? Admit it – you're dying to know. Developers can now create applications that not only process text or voice but also interpret and generate responses based on visual cues, and importantly fine tuned for domain specific applications, and this update could lead to more intuitive user interfaces in applications, where users can interact with services using images as naturally as they do with text or speech, potentially expanding the user base to those less tech-savvy or in fields where visual data is crucial. 03:53 Jonathan – “I mean, I think it’s useful for things like quality assurance in manufacturing, for example. You know, could, you could tune it on what your nuts and bolts are supposed to look like and what a good bolt looks like and what a bad bolt looks like coming out of the factory.

In his regular monthly spot on PING, APNIC's Chief Scientist, Geoff Huston, discusses a large pool of IPv4 addresses left in the IANA registry, from the classful allocation days back in the mid 1980s. This block, from 240.0.0.0 to 255.255.255.255 encompasses 268 million hosts, which is a significant chunk of address space: it's equivalent to 16 class-A blocks, each of 16 million hosts. Seems a shame to waste it, how about we get this back into use? Back in 2007 Geoff Paul and myself submitted An IETF Draft which would have removed these addresses from the "reserved" status in IANA and used to supplement the RFC1918 private use block. We felt at the time this was the best use of these addresses because of their apparent un-routability, in the global internet. Almost all IP network stacks at that time shared a lineage with the BSD network code developed at the University of California, and released in 1983 as BSD4.2. Subsequent versions of this codebase included a 2 or 3 line rule inside the Kernel which checked the top 4 bits of the 32 bit address field, and refused to forward packets which had these 4 bits set. This reflected the IANA status marking this range as reserved. The draft did not achieve consensus. A more recent proposal has emerged from Seth Schoen, David Täht and John Gilmore in 2021 which continues to be worked on, but rather than assigning to RFC1918 internal non-routable puts the address into global unicast use. The authors believe that the critical filter in devices has now been lifted, and no longer persists at large in the BSD and Linux derived codebases. This echoes use of the address space which has been noted inside the Datacentre. Geoff has been measuring reachability at large to this address space, using the APNIC Labs measurement system and a prefix in 240.0.0.0/4 temporarily assigned and routed in BGP. The results were not encouraging, and Geoff thinks routability of the range remains a very high burden.

Host Philip Gervasi talks with Doug Madory and Job Snijders about the importance of RPKI in securing Internet routing. They explore the recent milestone of RPKI covering 50% of IPv4 routes, the process of route origin validation (ROV), and the role of ROAs. They also discuss the impact of ROA expirations and future advances in Internet routing security. Tune in to learn how RPKI contributes to a more stable and secure Internet.
Welcome to episode 261 of the Cloud Pod podcast – where the forecast is always cloudy! Justin, Matthew, and Ryan are your hosts this week, and there's a ton of news to cover, including a slew of Azure and Oracle stories! This week the guys cover some new cost management strategies from FinOps, some Kubernetes updates, MS Build, and even fancy schmancy CoPilot PCs! Titles we almost went with this week: Azure woke up and announced things AWS stops taking your IPv4 Money Well now everything has copilot A big thanks to this week's sponsor: Big thanks to Sonrai Security for sponsoring today's podcast! Check out Sonrai Securities’ new Cloud Permission Firewall. Just for our listeners, enjoy a 14 day trial at https://sonrai.co/cloudpod AWS 00:57 AWS plans to invest €7.8B into the AWS European Sovereign Cloud, set to launch by the end of 2025 Amazon is sharing more details about the AWS European Sovereign Cloud roadmap so that customers and partners can start planning. The first AWS European Sovereign Cloud is planning to launch its first AWS Region in the state of Brandenburg, Germany by the end of 2025. Available to all AWS customers, this effort is backed by a 7.8B Euro investment in infrastructure, jobs and skills development. Customers will get the full power of the AWS architecture, expansive service portfolio and API's that customers use today. Customers can start building applications in any existing Region and simply move them to AWS European Sovereign Cloud when the first region launches in 2025. And how exactly will they do that, you might be wondering? If you mean there will be an easy button that’s awesome… do it everywhere else. if you mean update Terraform and redeployed Screw you, Amazon. 03:23 Ryan – “Yeah. It just seems so anti what they’re trying to set up with the sovereign region to begin with, right? Like, I guess copying data is fine in, but not out. Like it’s sort of, it’s like GovCloud, right? It’s completely separate. So strange.” 05:06 Application Load Balancer launches IPv6-only support for Internet clients ALB's now allow you to provision load balancers without IPV4 for clients that can connect using just IPv6. Woot. 05:25 Ryan – “So the trick is for internal, the reason why we’re starting to see this more and more is that because you can address these huge spaces in IPv6, they’re not doing the equivalent of RFC 1918 address space. So that’s why these things become super important because they’ll configure an internal sort of networking path that

These days, most network devices can speak both IPv4 and IPv6. A dual-stack approach can smooth the transition from one protocol to the other because organizations can get comfortable with IPv6 without having to make a hard cutover. However, they may get so comfortable that they never fully commit. In this episode Ed, Scott, and... Read more »
