AUSNOG’23 was held in September. As usual, the meeting had a diverse collection of presentations on network technology, operational practices, engineering, and experiences. One of these presentations, by Cloudflare’s Tom Peseka, was on the subject of service routing, highlighting the ways in which today’s service platform attempt to optimise the…
The canonical specification of the DNS that is normally cited are the pair of quite venerable RFCs, RFC 1034, “Domain names – concepts and facilities”, and RFC 1035, “Domain names – implementation and specification”, both published in November 1987. However, these two specification documents are just the tip of a…

I attended a workshop on the topic of Internet Fragmentation in July. The workshop was attended by a small collection of Australian public policy folk, some industry representatives, folk from various cyber-related bodies and those who have a background in Internet Governance matters. It was a short meeting, so the…
The DNS is a strange and at times surprising environment. One could take a simple perspective and claim that the aim of the DNS is to translate DNS names into IP addresses. And you wouldn’t be wrong, but it’s also so much more. The DNS is also used as a…
Some 50 years ago, at the Palo Alto Research Centre of that renowned photocopier company Xerox, a revolutionary approach to local digital networks was born. On the 22nd of May 1973 Bob Metcalf authored a memo that described “X-Wire”, a 3Mbps common bus office network system developed at Xerox’s Palo…
Following the publication of RFC 7872 in 2016, a number of research teams have been looking at the nature of network and host behaviours in discarding IPv6 packets with various Extension Headers (EH). The findings reported in RFC 7872 were a significant level of packet loss (“significant” being above 10%…
