The first part of this annual 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…
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.…
This is a report on a feasibility study looking at an alternative trust anchor structure for the Resource Public Key Infrastructure (RPKI). Background In the early days of the Internet in the 1980’s when the Internet address plan used the Class A, B and C address structure, it appears that…
The IETF met in Prague in the first week of November 2023. I attended the meeting of the Measurement and Analysis of Protocols Research Group, and here are my impressions from that meeting. QUIC Topics QUIC is essentially a variant of TCP, but at the same time it also represents…
The IETF met in Prague in the first week of November 2023, and, as usual there was a flurry of activity in the DNS-related Working groups. Here’s a roundup of those DNS topics I found to be of interest at that meeting. Re-thinking the DNS Prior to IETF meetings there…
There was a somewhat unfortunate outage for a major communications service provider in Australia, Optus, in mid-November. It appears that one of their peer BGP networks mistakenly advertised a very large route collection to the Optus BGP network which caused the routers to malfunction in some manner. The problem was…
There was a draft that caught my attention during DNSOPS Working Group session at the recent IETF 118 meeting on the topic of “DNS IPv6 Transport Operational Guidelines”. This draft proposes to update an earlier guideline document with some new guidelines. The original document, RFC3901, titled “DNS IPv6 Transport Guidelines””,…
At APNIC Labs we publish a number of measurements of the deployment of various technologies that are being adopted on the Internet. Here we will look at how we measure the adoption of the signing of Route Origination Attestations (ROAs) as part of the framework for securing inter-domain routing on…
At APNIC Labs we publish a number of measurements of the deployment of various technologies that are being adopted on the Internet. Here we will look at how we measure the adoption of DNSSEC validation. DNSSEC Security for the DNS has been a vexed topic for many years. The days…
Trust is such a difficult concept in any context, and certainly computer networks are no exception. How can you be assured that your network infrastructure us running on authentic platforms, both hardware and software, and its operation has not been compromised in any way? The combination of complex supply chains…
