March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days where too much DNS is just not enough! These workshops are a concentrated two days of presentations and discussions that focus exclusively in the current state of the DNS.…
I’ve been prompted to write this brief opinion piece in response to a recent article posted on CircleID by Tony Rutkowski, where he characterises the IETF as a collection of “crypto zealots”. He offers the view that the IETF is behaving irresponsibly in attempting to place as much of the…
The story about securing the DNS has a rich and, in Internet terms, protracted history. The original problem statement was simple: how can you tell if the answer you get from your query to the DNS system is ‘genuine’ or not? The DNS alone can’t help here. You ask a…
Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. There is no doubt that the…
It has become either a tradition, or a habit, each January for me to report on the experience with the inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection…
In the United States the debate between advocates of market-based resolution of competitive tensions and regulatory intervention has seldom reached the fever pitch that we’ve seen over the vexed on-again off-again question of Net Neutrality in recent weeks. It seems as it the process of determination of communications policy has…

I’m sure that this comment could apply to many countries, including Australia with their political football called the National Broadband Network. But…
In this final article of a trio that looks at today’s “hot” topics in the DNS, I’d like to look at ways that recursive resolvers in the DNS can take some further steps that assist other parts of the DNS, notably the set of authoritative name servers, including root zone…
Among all the working groups that met at IETF 100 in Singapore was the first meeting of the DNS over HTTPs Working Group (DOH). I wrote on a related topic of DNS Privacy a little over a year ago, looking at the work at the time on the privacy-related topics…
The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark in terms of the sorry history of “landmark” DDOS attacks in the Internet. It’s up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009…
