In this episode, we talk with Adrian Farrel about a study he and Daniel King conducted on the challenges semantic routing has had on the Internet's routing system.Now, this is a topic that a lot of people have a poor opinion of, particularly its link to New IP (https://blog.apnic.net/2020/05/25/new-ip-and-emerging-communications-technologies/). But what this study hopes to achieve is to look past the preconceptions and discover the broad underlying issues that semantic routing proposals are seeking to address and how to do it in a generic and scalable way that doesn’t break the network layer.Further to this, it also seeks to shed a light on the standard system and how to introduce new ideas before shooting them down as inappropriate.You can read more about this study on the APNIC Blog (https://blog.apnic.net/?s=semantic+routing) or via the following sources:* An Introduction to Semantic Routing (https://gate.sc?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-farrel-irtf-introduction-to-semantic-routing%2F&token=cd7e5a-1-1654660769555)* A Survey of Semantic Internet Routing Techniques (https://gate.sc?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-king-irtf-semantic-routing-survey%2F&token=1b30f9-1-1654660769555)* Challenges for the Internet Routing Systems Introduced by Semantic Routing (https://gate.sc?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-king-irtf-challenges-in-routing%2F&token=258f71-1-1654660769555)Also, there is a free virtual IETF Routing Area Working Group (RTGWG) interim meeting (https://datatracker.ietf.org/doc/agenda-interim-2022-rtgwg-01-rtgwg-01/) on 21 June 2022 (15:00 to 17:00 UTC) to discuss semantic routing.The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

Geoff Huston joins us again for his monthly chat, this time to consider the contradictory theory of a resolverless DNS. Contradictory because the DNS is by its nature reliant on resolvers.We'll discuss the historical process of how DNS names are resolved and how content providers, through their open DNS services, have sought to optimise this process. This optimisation has led some, including Geoff, to consider 'server push' combined with DNSSEC, as a viable means to speed up the DNS, reduce privacy leakage and constrain the potential for failures.You can read more on the APNIC Blog The path to resolverless DNS (https://blog.apnic.net/2022/05/17/the-path-to-resolverless-dns/).The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our fourteenth episode, we're taking a closer look at Resource Public Key Infrastructure (RPKI) in Australia and New Zealand with Terry Sweetser.Terry recently worked on an Internet Society project to measure RPKI adoption in Australia and New Zealand among its government services and critical infrastructure. We've invited him on to discuss the results and research methodology, including the challenges of working with public sources of data.Watch (2022.apricot.net/program/schedule%E2%80%A6curity-sig-forum) Terry's presentation on this project at APRICOT 2022 and check out the RPKI @ APNIC (https://www.apnic.net/rpki-at-apnic/?utm_source=podcast&utm_medium=organic&utm_campaign=rpki@apnic&utm_content=campaign) portal for more information on RPKI as well as useful deployment case studies, how-to posts and links to hands-on APNIC Academy lessons and labs.The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our thirteenth episode, Geoff Huston joins us again for his monthly chat, this time on the historical feudings between carriers and content providers.The latest instalment in this feud is currently playing out in Korea, where South Korean Internet Service Provider, SK Broadband, is suing Netflix (https://www.reuters.com/business/media-telecom/skorea-broadband-firm-sues-netflix-after-traffic-surge-squid-game-2021-10-01/)to pay for the costs of increased network traffic and maintenance work because of a surge in viewers since 2018.For Geoff, this is merely the latest in a long list of disputes dating back to the 1800s that have regularly been decided by the courts and regulators. But this most recent dispute is being watched closely by all sides around the world with Korean regulators taking a different and deliberate road that for some impedes the free market regulation model that has made the Internet into what it is today.You can read more about Korea's network regulations in Afterword: Korea’s Challenge to the Standard Internet Interconnection Model (https://carnegieendowment.org/2021/08/17/afterword-korea-s-challenge-to-standard-internet-interconnection-model-pub-85166).The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our twelfth episode, we're talking all things Resource Public Key Infrastructure (RPKI) with Job Snijders, Principal Engineer at Fastly.Job shares his thoughts on the benefits of managing an RPKI publication point, including the experience and insights it can give you. We also touch on a recent IETF proposal he has assisted with that seeks to provide clearer, authenticated proof of the intent by address delegates and the future of routing securing including IRR and BGPsec.Check out RPKI @ APNIC (https://www.apnic.net/rpki-at-apnic/?utm_source=podcast&utm_medium=organic&utm_campaign=rpki@apnic&utm_content=campaign) portal for more information on RPKI as well as useful deployment case studies, how-to posts and links to hands-on APNIC Academy lessons and labs.The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our eleventh episode, we are again talking to APNIC's Chief Scientist, Geoff Huston, this time about certificate revocation.This has been a hotly debated subject for some time, namely whether it still serves a purpose given that many web browsers give you the option to ignore revoked certificates or ignore them for you. We'll discuss this and possible solutions to addressing the revocation processes issues.You can read more about certificate revocation on the APNIC Blog (https://blog.apnic.net/?s=certificate+revocation), including a post from Geoff: What’s going on with certificate revocation? (https://blog.apnic.net/2022/03/22/whats-going-on-with-certificate-revocation/)The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our tenth episode, we're talking all things submarine cables with Alan Mauldin, who is a Research Director at TeleGeography.Synonymous with their submarine cable maps, TeleGeography also offers a range of open-source data surrounding the health of the Internet, as we'll come to learn.Read about the latest submarine cable research (https://blog.apnic.net/tag/submarine-cable/) on the APNIC Blog.The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

In our ninth episode, APNIC's Chief Scientist, Geoff Huston, and I chat with Reliance Jio's Senior Executive Vice President, Mr Nagaraj, who oversees the design, architecture and engineer of Jio's IP network as well as operational support.With more than 420 million mobile users and 260 million cable users, Reliance Jio has grown to become one of the largest telcos in the world in less than a decade. How were they able to do this in the age of IPv4 exhaustion? By deploying IPv6 from the get-go. Mr Nagaraj takes us through the discussions he had in convincing his management and vendors to go IPv6 and the future of the Jio network, including working more closely with content providers to bring content closer to users than before.You can also read an abbreviated transcript of this discussion on the APNIC Blog: https://blog.apnic.net/2022/03/03/podcast-taking-ipv6-by-the-horns/ (https://blog.apnic.net/2022/03/03/podcast-taking-ipv6-by-the-horns/)The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.
