Some not-DNS Topics at IETF 111

I’ve already scribed my thoughts on the DNS-related topics that were discussed at the July 2021 IETF 111 meeting. It may be surprising to the DNSphiles out there but there really are other topics that are discussed at IETF meetings not directly related to the DNS! These are some notes…


DNS at IETF 111

IETF 111 was held virtually in July 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 111. DNSOP – DNS Operations DNSOP is the general working group for most DNS topics and…

Network Protocols and their Use

In June I participated in a workshop, organized by the Internet Architecture Board, on the topic of protocol design and effect, looking at the differences between initial design expectations and deployment realities. These are my impressions of the discussions that took place at this workshop. 1 – Case Studies In…


Just One Bit

I’m never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the…
