PING

PING is a podcast for people who want to look behind the scenes into the workings of the Internet. Each fortnight we will chat with people who have built and are improving the health of the Internet. The views expressed by the featured speakers are their own and do not necessarily reflect the views of APNIC.

Calling time on DNSSEC: Part 1 of 2

Calling time on DNSSEC: Part 1 of 2

In his regular monthly spot on PING, APNIC’s Chief Scientist Geoff Huston discusses DNSSEC and it's apparent failure to deploy at scale in the market after 30 years: Both as the state of signed zone uptake (the supply side) and the low levels of verification seen by DNS client users (the consumption side) there is a strong signal DNSSEC isn't making way, compared to the uptake of TLS which is now ubiquitous in connecting to websites. Geoff can see this by measurement of client DNSSEC use in the APNIC Labs measurement system, and from tests of the DNS behind the...

The check is in the (e)Mail(s)

The check is in the (e)Mail(s)

This time on PING, Philip Paeps from the FreeBSD Cluster Administrators and Security teams discusses their approach to systems monitoring and measurement. Its eMail.


“Short podcast” you say, but no, there’s a wealth of war-stories and “why” to explore in this episode.


We caught up at the APNIC57/APRICOT meeting held in Bangkok in February of 2024. Philip has a wealth of experience in systems management and security and a long history of participation in the free software movement. So his ongoing of support of email as a fundamental measure of syst...

We don't need subnets any more

We don't need subnets any more

In his regular monthly spot on PING, APNIC’s Chief Scientist Geoff Huston discusses the question of subnet structure, looking into the APNIC Labs measurement data which collects around 8 million discrete IPv6 addresses per day, worldwide.


Subnets are a concept which "came along for the ride" in the birth of Internet Protocol, and were baked into the address distribution model as the class-A, class-B and class-C subnet models (there are also class-D and class-E addresses we don't talk about much).


The idea of a sub-net is distinct from a rout...

Measuring RPKI and BGP with Oregon RouteViews

Measuring RPKI and BGP with Oregon RouteViews

This time on PING Doug Madory from Kentik discusses his recent measurements of the RPKI system worldwide, and it's visible impact on the stability and security of BGP.


Doug makes significant use of the Oregon RouteViews repository of BGP data, a collection maintained continuously at the University of Oregon for decades. It includes data from back to 1997, originally collected by the NLANR/MOAT project and has archives of BGP Routing Information Base (RIB) dumps taken every two hours from a variety of sources, and made available in both human-readable and machine readable binary formats.<...

Measuring Starlink TCP performance

Measuring Starlink TCP performance

In this episode of PING, APNIC’s Chief Scientist Geoff Huston discusses Starlink again, and the ability of modern TCP flow control algorithms to cope with the highly variant loss and delay seen over this satellite network. Geoff has been doing more measurements using starlink terminals in Australia and the USA, at different times of day exploring the system behaviour.


Starlink has broken new ground in Low Earth Orbit internet services. Unlike Geosynchronous satellite services which have a long delay but constant visibility of the satellite in stationary orbit above, Starlink requires the consumer to c...

Using Fibre Optics to measure vehicle traffic

Using Fibre Optics to measure vehicle traffic

This time on PING, Dr Mona Jaber from Queen Mary University of London (QMUL), discusses her work exploring IoT, Digital Twins and Social Science led research in the field of networking and telecommunications.


Dr Jaber is a senior lecturer in QMUL and is the founder and director of the Digital Twins for Sustainable Development Goals (DT4SDG) at QMUL. She was one of the invited Keynote speakers at the recent APRICOT/APNIC57 meeting held in Bangkok, and the podcast explores the three major themes explored in her keynote presentation.

The role of deployed f...

Digital sovereignty and standards

Digital sovereignty and standards

In this episode of PING, APNIC’s Chief Scientist Geoff Huston discusses the European Union's consideration of taking a role in the IETF, as itself. Network engineers, policy makers and scientists from all around the world have participated in IETF but this is the first time an entity like the EU has considered participation as itself in the process of standards development. 


What's lead to this outcome? What is driving the concern that the EU as a law setting and treaty body, an inter-governmental trade bloc needs to participate in the IETF process? Is this...

DNS OARC's many faces

DNS OARC's many faces

This time on PING we have Phil Regnauld from DNS Operations Analysis & Resource Center (DNS-OARC) talking about the three distinct faces OARC presents to the community.


Phil came to the OARC presidents role, replacing Keith Mitchell who was the founding president since 2008 through to this year. Phil previously has worked with the Network Startup Resource Centre (NSRC) and with AFNOG, and the Francophone Internet community at large.


DNS OARC has at least 3 distinct faces. It is a community of DNS operators and researchers, who maintain an active ongoing dialogue fa...

DELEG

DELEG

In this episode of PING, APNICs Chief Scientist Geoff Huston discusses a new proposed DNS resource record called DELEG. The record is being designed to aid in managing where a DNS zone is delegated.


Delegation is the primary mechanism used in the DNS to separate responsibility between child and parent for a given domain name. The DELEG RR is designed to address several problems, including a goal of moving to new transports for the name resolution service the DNS provides to all other Internet protocols.


Additionally, Geoff believes it...

Taking the PULSE of the Internet

Taking the PULSE of the Internet

This time on PING we have Amreesh Phokeer from the Internet Society (ISOC) talking about a system they operate called Pulse, available at https://pulse.internetsociety.org/. Pulse’s purpose is to assess the “resiliency” of the Internet in a given locality.

Similar systems we have discussed before on Ping include APNIC’s DASH service, aimed at resource holding APNIC members, and the MANRS project. Both of these take underlying statistics like resource distribution data, or measurements of RPKI uptake or BGP behaviours and present them to the community, and in the case of MANRS there’s a formalised “sco...
