Once the realisation sunk in that the lockdown response to the COVID-19 pandemic was not a short-term hiatus in our lives but a new normal, at least for a while, then a set of meetings and workshops have headed into the online space. For many years I have been a…
By Joao Damas and Geoff Huston At NANOG 79 earlier this month Craig Labowitz from Nokia Deepfield presented on the impact on the COVID-19 pandemic on Internet use. The approach to the analysis used real time streaming telemetry from Communication Service Provider (CSP) backbone and aggregation routers and the…
One year ago, I looked at the state of adoption of DNSSEC validation in DNS resolvers and the answer was not unreservedly optimistic. Instead of the “up and to the right” curves that show a momentum of adoption, there was a pronounced slowing down across 2017 and the first half…
DNS OARC held its 31st meeting in Austin, Texas on 31 October to 1 November. Here are some of my highlights from two full days of DNS presentations at this workshop. Building a New Nameserver There are two parts to DNS infrastructure. One is the infrastructure that supports resolving queries…
NANOG is now quite an institution in the Internet, particularly in the North American Internet community. It was an offshoot of the Regional Techs meetings, which were part of the NSFNET framework of the late 80s and early 90s. NANOG has thrived since then and is certainly one of the…

Much has been said and written in recent times about the use of the DNS as a means of looking at the behaviour of end systems and inferring user behaviours. Almost every transaction starts with a DNS query, and if one were to assemble the complete set of DNS queries…
DNSSEC is often viewed as a solution looking for a problem. It seems only logical that there is some intrinsic value in being able to explicitly verify the veracity and currency of responses received from DNS queries, yet fleshing this proposition out with practical examples has proved challenging. The relatively…
DNS OARC held its 30th meeting in Bangkok on the 12th and 13th May. Here’s what attracted my interest from two full days of DNS presentations and conversations, together with a summary of the other material that was presented at this workshop. Some Bad News for DANE (and DNSSEC) For…
By any metric, the queries and responses that take place in the DNS are highly informative of the Internet and its use. But perhaps the level of interdependencies in this space is richer than we might think. When the IETF considered a proposal to explicitly withhold certain top level domains…
