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…
IETF 110 was held virtually in March 2020. These are some notes I took on the topic of current activities in the area of the Domain Name System and its continuing refinement at IETF 110. The amount of activity in the DNS in the IETF seems to be growing every…
IETF 110 was held virtually in March 2020. These are some notes I took on the topic of current research activities in the area of transport protocol flow control at the meeting of the Internet Congestion Control Research Group at that meeting. HPCC+: High Precision Congestion Control In the early…
There are a number of parts to the current framework that we’re using to improve routing security on the Internet.

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…
It’s often a clear signal that we’re in in deep trouble when politicians believe that they need to lend a hand and help out with regulations. A bill has been passed by the US Congress, and now signed into law, that requires the National Institute of Science and Technology to…
