There was a meeting of DNS Operations and Research group in February, DNS-OARC 37. These are my notes from the presentations that I found to be of interest. Zone File Bug Hunting The DNS is deceptively simple. Simple, in that are few choices in how to configure the zone information…
I bet that nobody believed in 1992 that thirty years later we’d still be discussing the state of the transition to IPv6! In 1992 we were discussing what to do about the forthcoming address crunch in IPv4 and having come to terms with the inevitable prospect that the silicon industry…
The last few decades have not been a story of unqualified success for European technology enterprises. The European industrial giants of the old telephone world, such as the former stalwarts Alcatel, Siemens, Philips, Ericsson and Nokia, have found it to be extraordinarily difficult to translate their former dominant positions in…
I work at APNIC, the Regional Internet Registry that serves the Asia Pacific Region. APNIC provides common infrastructure services for the region that support the unique assignment of IP address blocks to Internet network operators within our region through the operation of an address registry. In short, IP addresses are…
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…
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…
At the start of each year, I have been reporting on the behaviour of the inter-domain routing system over the past 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.…
ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here. DNS Resolver Evolution The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System,…
Something odd happened through 2021 in the market for IPv4 addresses. Across 2021 the reported market price for the transfer of IPv4 addresses has doubled, from approximately USD27 per IPv4 individual address at the end of 2020 to around USD55 per address in December 2021. It has taken 7 years…
It’s conference and workshop season right now, and November has been unusually busy this year. At the end of the month was the DNS Operations and Research meeting, DNS-OARC 36. These are my notes from those presentations that I found to be of interest. Slack’s DNSSEC Debacle It’s a pretty…
