The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF…
The Internet’s Domain Name System undertakes a vitally important role in today’s Internet. Originally conceived as a human-friendly way of specifying the location of the other end of an Internet transaction, it became the name of a service point during the transition to a client/server architecture. A domain name was…
In August 1858, Queen Victoria sent the first transatlantic telegram to U.S. President James Buchanan. The cable system had taken a total of four years to build, and used 7 copper wires, wrapped in a sheath of gutta percha, then covered with a tarred hemp wrap and then sheathed in…
I’d like to reflect on a presentation by Dr. Paul Vixie at the October 2022 meeting of the North American Network Operators Group (NANOG), on the topic of the shift to pervasive encryption of application transactions on the Internet today. There is a view out there that any useful public…

I’d like to update our earlier report on this topic with some more recent measurement data. These extensions to the basic IPv6 packet header have their antecedents in the IPv4 option fields.…
In policy work nothing is ever truly simply black and white. The means to achieve one outcome may well act to impair the work to achieve different outcomes, and the resultant effort often requires some difficult decisions to balance what appears to be some fundamental tensions between various policy objectives.…
There is no single name system that is necessarily bound to the Internet. Unlike IP addresses which are in every IP packet, names are an application construct, and, in theory, applications have considerable latitude in how they handle such names. There could be many name systems that could coexist within…
One of the discussion topics at the recent ICANN 75 meeting was an old favourite of mine, namely the topic of Internet Fragmentation. Here, I’d like to explore this topic in a little more detail and look behind the kneejerk response of declaiming fragmentation as bad under any and all…
