The original specification of the BGP routing protocol, RFC 1105, from 1989, has the following directive: “NOTIFICATION messages are sent when an error condition is detected. The BGP connection is closed shortly after sending the notification message.” Ahh, you might think, that might be a potential problem, but the directive…
It’s been an interesting couple of weeks for me in mid-October 2023. I presented in a couple of panels at the 18th Internet Governance Forum meeting, held in Kyoto, Japan, and I also listened in to a couple of sessions in their packed agenda. The following week I followed the…
OARC held a 2-day meeting in September in Danang, Vietnam, with a set of presentations on various DNS topics. Here’s some observations that I picked up from the presentations that were made that meeting. Deploying ZONEMD in the Root Zone As a distributed database, the DNS works through the piecemeal…
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.

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…
