In the last episode of PING for 2024, APNIC’s Chief Scientist Geoff Huston discusses the shift from existing public-private key cryptography using the RSA and ECC algorithms to the world of ‘Post Quantum Cryptography. These new algorithms are designed to withstand potential attacks from large-scale quantum computers and are capable of implementing Shor’s algorithm, a theoretical approach for using quantum computing to break the cryptographic keys of RSA and ECC. Standards agencies like NIST are ...

This time on PING, Peter Thomassen from SSE and DEsec.io discusses his analysis of the failure modes of CDS and CDNSKEY records between parent and child in the DNS. These records are used to provide in-band signalling of the DS record, fundamental to the maintenance of a secure path from the trust anchor to the delegation through all the intermediate parent and grandparent domains. Many people use out-of-band methods to update this DS information, but the CDS and the CDNSKEY records are designed...

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 no...

In this episode of PING, Vanessa Fernandez and Kavya Bhat, two students from the National Institute of Technology Karnataka (NITK) discuss the student led, multi-year project to deploy IPv6 at their campus. Kavya & Vanessa have just graduated, and are moving into their next stages of work and study in computer sciences and network engineering. Across 2023 and 2024 they were able to attend IETF118 and IETF119 and present on their project and it’s experiences to the IPv6 working groups and off-Wor...

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...

In this episode of PING, Nowmay Opalinski from the French Institute of Geopolitics at Paris 8 University discusses his work on resilience, or rather the lack of it, confronting the Internet in Pakistan. As discussed in his blog post, Nowmay and his colleagues at the French Institute of Geopolitics (IFG), University Paris 8, and LUMS University Pakistan used a combination of technical measurement from sources such as RIPE Atlas, in a methodology devised by the GEODE project, combined with intervi...
