This is part of a personal commentary on the meetings at the July 2023 meeting of the Internet Engineering Task Force (IETF 117). If you want to know what was presented and the comments at the mic see the IETF 117 meeting archive. The IEPG meets for a couple of…
Following the publication of RFC 7872 in 2016, a number of research teams have been looking at the nature of network and host behaviours in discarding IPv6 packets with various Extension Headers (EH). The findings reported in RFC 7872 were a significant level of packet loss (“significant” being above 10%…
The topic of the robustness of IPv6 Extension Headers has experienced a resurgence of interest in recent months. I’d like to update our earlier report on this topic with some more recent measurement data. These extensions to the basic IPv6 packet header have their antecedents in the IPv4 option fields.…
The saga of the IPv6 transition continues to surprise us all. RFC 2460, the first complete effort at a specification of the IPv6 protocol was published in December 1998, more than twenty years ago. The entire point of IPv6 was to specify a successor protocol to IPv4 due to the…
It is a rare situation when you can create an outcome from two somewhat broken technologies where the outcome is not also broken. Unless each of the components can precisely complement each other such that a weakness in one can be covered by a strength in the other, then the…
I bet that nobody believed in 1992 that thirty years later we’d still be discussing the state of the transition to IPv6! In 1992 we were discussing what to do about the forthcoming address crunch in IPv4 and having come to terms with the inevitable prospect that the silicon industry…
The RIPE community held a meeting in November. Like most community meetings in these Covid-blighted times it was a virtual meeting. Here’s my notes from a few presentations that piqued my interest. All the material presented at the meeting can be found at https://ripe83.ripe.net/. Vulnerability Disclosure Responsible Disclosure is a…
Committees should never attempt to define technology There always seems to be a point in the process where there is a choice between two quite different options, and there is no convincing case that one choice is outstandingly better than the other. Committees find it terribly hard to decide at…
The Australian Domain Name Administration, AUDA, has recently published its quarterly report for the last quarter of 2020. The report contained the interesting snippet: “The rapid digitisation of our lives and economy – necessitated by COVID-19 – continued to underpin strong growth in .au registrations. New .au domains created in…
These days it seems that whenever we start to talk about the DNS the conversation immediately swings around to the subject of DNS over HTTPS (DoH) and the various implications of this technology in terms of changes in the way the DNS is used. It’s true that DoH is a…
