Modern service discovery mechanisms increasingly allow services to run on arbitrary ports, yet DNS may remain the one protocol that cannot fully escape its dependency on the long-established convention of port 53.
A growing debate within the IETF is exploring how AI-generated content should be used and disclosed in standards discussions.
Guest Post: RPKI has made real progress against prefix hijacking. But when you map every known class of BGP attack against the defences that exist, four of them turn out to sit entirely outside cryptographic validation — handled with local filters, static thresholds and reactive response.
Guest Post: At IETF 126, discussions highlighted how AI is beginning to shape the future of Internet infrastructure. Participants identified IPv6 as a critical foundation for large-scale AI ecosystems and explored new approaches.
Guest Post: No homelab can be complete without a proper networking setup. Proceed at your own risk! (… it’s worth it)
IXPs shape latency, cost, resilience, and the spread of new technologies, not just Internet speed. As the Internet evolves, the role of IXPs continues to expand, as highlighted in this BPF 2026 panel discussion.
Geoff Huston discusses the unexpected behaviours of the DNS when you perform a query after ‘cold start’ with no cached data.
Guest Post: Privacy compliance starts with knowing your data. Many NREN services, including federated identity, eduroam, CSIRT operations, and network telemetry, process personal data and may already fall under emerging privacy laws.
Guest Post: Though often overlooked, time underpins telecommunications, finance, energy, cloud, AI, and transport systems. As dependence on GNSS increases, organizations need resilient, traceable time sources to strengthen cybersecurity, improve operational continuity, and support digital sovereignty.
Guest Post: Chamelio is a provider-managed network stack for cloud VMs that runs in userspace on the host and allows tenants to upload custom transport protocols to a shared datapath.
