After building private backbones, content and cloud platforms are now moving closer to users. In doing so, they are taking on delivery roles once associated mainly with independent CDNs.

There is a subtle asymmetry in IPv6 Neighbour Discovery: a host knows how to reach its router before the router necessarily knows how to reach the host. GRAND fixes that asymmetry by making the host proactively advertise its address, and I implemented that mechanism in FreeBSD.

Traceroute is a powerful tool for uncovering how packets travel across the Internet. However, as we recently discovered, some routers tamper with the TTL values in traceroute's probing packets, giving you a false view of how networks are actually interconnected.

Internet research can benefit from operational insight, and network operators from research expertise. Building on what we learned at RIPE 92, we look at practical ways to make those connections easier and turn promising conversations into lasting collaboration.

In the third part of our IRR landscape series, we use traffic measurements from AMS-IX and DE-CIX to assess which parts of the IRR landscape can safely be replaced with RPKI. Third-party ROUTE(6) objects can largely be phased out, while third-party AS-SETs remain essential for BGP filter generation.

Evidence suggests that criminals may control a substantial share of new gTLD registrations. Although the precise scale remains contested, the article asks whether current DNS Abuse measures adequately address wider misuse of domain names.

In this field report on IPv6-first Amazon Elastic Kubernetes Service (EKS), the isp6 team shares which dependencies still drag IPv4 back in, what they learnt from /28s, and why the saving is large but not automatic.

Why a feature introduced for a handful of members became one of the RIPE NCC's most complex operational challenges.
