The first part of this annual report on BGP for the year 2025 looked at the size of the routing table and some projections of table 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…
At the start of each year, it’s been my practice to report 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…
Where are you? Or, for that matter, where am I? Let’s look at location on the Internet, and how the Internet “knows” where I am. With devices that have GNSS (Global Navigation Satellite System) enabled, such as my mobile device, where I am is an easy question to answer. If…
The North American Network Operators Group (NANOG) can trace its antecedents to the group of so-called “Mid Level” networks that acted as feeder networks for the NSFNET, the backbone of the North American Internet in the first part of the 1990’s. NANOG’S first meeting has held in June 1994, and…
In September 2025 I wrote an article on Starlink and geolocation. This work was prompted by a question relating to the makeup of ISPs in the country of Yemen, where the data analysis point to a result where Starlink had some 6 million users in that country, or some 60%…
At APNIC Labs we publish a number of measurements of the deployment of various technologies that are being adopted on the Internet. Here I will look at how we measure the adoption of IPv6. IPv6 By 1990 it was clear that IP had a problem. It was still a tiny…
This article is based on a presentation I made to the ARIN 56 meeting in October 2025. Here I’d like to elevate the typical Regional Internet Registry policy conversations above the day-to-day mundanities of address allocation policies with its vocabulary of address block sizes and needs-based justifications, fairness and efficiency…
The 91st meeting of the RIPE community was held in Bucharest in October this year. It was a busy week and, as usual, there were presentations on a wide variety of topics, including routing, the DNS, network operations, security, measurement and address policies. The following are some notes on presentations…
“Where are you?” is not an easy question to answer on the Internet. The telephone system’s address plan embedded a certain amount of physical location information in the fixed line network, and a full E.164 telephone number indicated your location in terms of your country, and your area within that…
The Australian Network Operators’ Group, AUSNOG, just held its 19th meeting. Rather than simply relate the content of the presentations I’d like to take a few presentations and place them into a broader context to show how such topics fit today’s networked environment. Network Operations and Data Centres Perhaps unsurprisingly…
