The current program of building AI infrastructure is not cheap. The projected infrastructure spend in the 7-year period from 2025 to 2032 is projected to be $10.3 trillion in the US alone. The average investment would be at a level of almost 4% of US GDP, larger than previous national landmark boom investments in rail, electrification, transportation and telecommunications infrastructure. Can we afford it?
The answer to the question of just how many DNS nameservers should you use to serve a zone seems to be buried more in folklore than data! Let's see if there is a measurable difference between serving a zone with one or two nameservers.
What part of “No!” is so hard for the DNS understand? When we look at the way the DNS behaves when it is given a negative answer, we see that many DNS resolvers struggle with this and repeat the query. Here we will look at the different ways to say "No" and the number of repeat queries that are seen with each of these negative responses.
The IETF does not launch rockets, or design spacecraft, or even work on radio systems and spectrum assignment, but it has been engaged in the standardisation of communications protocols used to communicate with these spacecraft. Here's a few topics that were presented at IETF 126.
The 126th meeting of the Internet Engineering Task Force (IETF) was held in Vienna at the end of July 2026. It’s a busy week with a large number of meetings and conversations. These are some notes from sessions that had BGP-related content that I found to be of interest.

If there is one universal law in internet infrastructure, it is that no good intention goes unpunished by the practical realities of legacy software maintenance.
The share price of SpaceX is some USD $164 per share, and if you multiply that price by the total number of shares in the company you get a market capitalisation of USD $2.163 trillion. The current estimate of the world's population is 8.264 billion people, so the share price of SpaceX is currently at a phenomenal USD $261 per head. Is this a rational valuation of SpaceX? Or do we have a classic bubble on our hands?
These days you could be excused by suspecting that the world has gone AI-mad, and if you were at the NANOG 97 meeting your suspicions would've only been confirmed! The topics discussed the design of the data centres used to generate the large language models that underpin today's AI tools and the application of AI tools in network operations.
These days the Internet operates with vast infrastructure of replicated data, and the only differentiator between order and chaos is the ability to impose consistency upon the data through synchronisation across the distributed publication points of the same data. What tools can we use to synchronize data across multiple instances? There are many ways of performing this function, and here I'd like to look at a number of approaches, their strengths and weaknesses and their applicability.
A presentation, by ISC's Ondřej Surý, at RIPE 92 was on the topic of DNS provisioning, looking at how to strike a balance between resilience and efficiency in the provisioning of nameservers of DNS zones and the performance of DNS resolvers. lets dive into this topic!

As a collection of inter-twined markets, aspects of the Internet have been prone to excessive market distortions where one, or a small clique, of providers in market sector become completely dominant to the extent that there is no effective competition and no possibility of admitting additional market entrants. This form of market dominance is often termed "centrality". How centralised is the DNS?

Much has been said about the use of the DNS as a means of tracking and controlling the online behaviour of users. The response has been to hide the DNS behind encrypted transport.
