IP Addresses through 2022

Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. Back around 1992 the IETF gazed…


BGP in 2022 – BGP Updates

The first part of this report looked at the size of the routing table and looked at some projections of its growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing…


BGP in 2022 – The Routing Table

At the start of each year, I’ve been reporting on the behaviour of the Internet’s inter-domain routing system over the previous 12 months, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.…


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…

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…
