The last few decades have not been a story of unqualified success for European technology enterprises. The European industrial giants of the old telephone world, such as the former stalwarts Alcatel, Siemens, Philips, Ericsson and Nokia, have found it to be extraordinarily difficult to translate their former dominant positions in…
ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here. DNS Resolver Evolution The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System,…
It’s conference and workshop season right now, and November has been unusually busy this year. At the end of the month was the DNS Operations and Research meeting, DNS-OARC 36. These are my notes from those presentations that I found to be of interest. Slack’s DNSSEC Debacle It’s a pretty…
From the recent writeup of the DNS work at the IETF its clear that there is a large amount of attention being focussed on the DNS. It’s not just an IETF conversation, or a DNS OARC conversation, but a conversation that involves a considerable amount of research activity as well.…
Virtual meetings continue in the IETF, and the latest one was IETF 112 in November. Here are notes from some selected working group meetings that caught my attention. And, yes, I should say at the outset that the DNS continues to catch a lot of my attention these days, so…
It has often been said of technology standards that the good thing is that there are just so many to pick from! The same is true, to perhaps a more limited extent, in the world of cryptography. The choices may not be quite so diverse, but there are still many…
When we deregulated the telephone industry, we replaced these national monopolies and their vertically bundled structures with a collection of separate enterprises whose actions are orchestrated by market forces rather than by the dictates of the incumbent monopoly telco. This was a comprehensive upheaval to the telecommunications industry, and one…
Let’s look at the operation of DNSSEC and its use of public key cryptographic algorithms. The DNSSEC specification does not define in advance which algorithm you should use to generate the digital signature records for a DNSSEC-signed zone. And that’s a very good thing. The issue here is that cryptographic…
These are some notes I took from the DNS OARC meeting held in September 2021. This was a short virtual meeting with six presentations, but for those of us missing a fix of heavy-duty DNS, it was very welcome in any case! DNS Security Mechanisms There isn’t a single approach…
Am I really talking to you? In a networked world that’s an important question. For example, where I’m located, when I look up the DNS name www.google.com I get the IPv6 address 2404:6800:4006:813::2004. This implies that when I send an IPv6 packet to this destination address I will reach a…
