DNS in the IGF

I don’t normally make the effort to attend the Internet Governance Forum gatherings these days. It seems to me that this forum continues to struggle for relevance. In my view it has never been able to realize an effective engagement with the set of actors who make up the supply…


Some Random Notes from IETF 115

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…


Looking at Centrality in the DNS

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…


The Fibre Optic Path

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…


Dark

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…


Comparing QUIC and TCP

There is a common view out there that the QUIC transport protocol (RFC 9000) is just another refinement to the original TCP transport protocol [1] [2]. I find it hard to agree with this sentiment, and for me QUIC represents a significant shift in the set of transport capabilities available…


Notes from OARC 39

OARC held its fall meeting in Belgrade on October 22 and 23. Here are my impressions of some of the presentations from that meeting. UI, UX, and the Registry/Registrar Landscape One of the major reforms introduced by ICANN in the world of DNS name management was the separation of registry…


IPv6 Extension Headers Revisited

The topic of the robustness of IPv6 Extension Headers has experienced a resurgence of interest in recent months. 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.…


Walking the Policy Tightrope

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.…


DNS Evolution: Innovation or Fragmentation?

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…
