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…
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. Back around 1992 the IETF gazed…
The first part of this report looked at the size of the routing table and looked at some projections of its growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing…
At the start of each year I have been reporting on the behaviour of the inter-domain routing system over the past 12 months, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.…
Technical development often comes in short intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn’t all that secure, and it wasn’t totally reliable,…
The architecture of the Internet took a highly radical step in the evolution of wide area communications protocols. Rather than placing much of the functionality into the network infrastructure and using network functions to emulate reliable edge-to-edge circuitry, the Internet Protocol used a network service model that was minimal and…
The first part of this report on the handling of large DNS responses looked at the behaviour of the DNS, and the interaction between recursive resolvers and authoritative name servers in particular and examined what happens when the DNS response is around the Internet’s de facto MTU size of 1,500…
For a group that works on network technologies it was always a bit odd that the IETF met in person three times a year. Didn’t we have enough trust in the efficacy in the technologies that we work on? I don’t think that is the case. I think the bandwidth…
We’ve written a number of times about the issues of managing packet sizes in packet-switched networks. It’s an interesting space that is an essential part of the design of packet-switched networks, and a space where we still seem to be searching for a robust design. This work has been prompted…
