We’ve released NSD 4.14.1 with more compact data storage for improved memory efficiency. Check the release notes: www.nlnetlabs.nl/projects/nsd... Willem also wrote a blog post explaining the approach and measurements showing the reduced memory footprint: blog.nlnetlabs.nl/smaller-fast...

DNSOP WG is planning a virtual interim to discuss two I-Ds: - draft-ietf-dnsop-structured-dns-error - draft-nottingham-public-resolver-errors See also announcement email on mailing list for planning details, mailarchive.ietf.org/arch/msg/dns...

OpenDNSSEC will reach End-of-Life in Oct 2027. Since 2010, it’s been a trusted DNSSEC signer, pioneering automated key management and zone signing. As operational needs evolved, maintenance became complex. Our focus now shifts to Cascade, a modern, efficient successor. nlnetlabs.nl/news/2025/Oc...

Kicking off this weekend in Madrid, #IETF123 began with the #IETFHackathon on Saturday and Sunday. A fantastic way to start the week coding and connecting. Nearly 500 people registered and almost 60 projects. The Hackathon rooms are buzzing!

Unbound 1.23.1 is out — a security update fixing the Rebirthday Attack (CVE‑2025‑5994), affecting DNS resolvers with ECS servers replying without ECS. Details: nlnetlabs.nl/downloads/un... Release: github.com/NLnetLabs/un... Thanks to Xiang Li for reporting!

...speaking about the Roto language: it was featured on the front page of Hacker News after @terts introduced it on our blog: blog.nlnetlabs.nl/introducing-...

Mijn grootvaders broer, Pieter Slooten, koos niet de makkelijke weg. Hij koos verzet. Vandaag denk ik aan hem, en aan allen die hun leven gaven voor iets groters dan henzelf. #4mei #dodenherdenking www.dodenakkers.nl/herdenkings-...

A new release of Rotonda, our composable, programmable #BGP engine, is now available. Version 0.4.0 'Bold and Undaunting Youth' features and #RPKI RTR component, as well as Route Origin Validation on incoming routes. github.com/NLnetLabs/ro...

NSD 4.12.0 is now available. Our authoritative #DNS server now offers Prometheus metrics, along with several other enhancements. github.com/NLnetLabs/ns...

Unbound 1.23.0 is out! Our #DNS resolver now supports 'fast reload'—it reads new configs in a thread and only briefly pauses to apply them. Also includes Redis replica support, DNS Error Reporting, and bug fixes. nlnetlabs.nl/news/2025/Ap...

Our Director of DNS Engineering, Ondřej Surý, is now a co-chair of the DNS operations working group in the IETF. Congratulations! datatracker.ietf.org/group/dnsop/...

Deadline extended to 29 April 2025 – still time to submit your papers

In equal honour to his induction into the Internet Hall of Fame, we have honoured our colleague of many years, Jaap Akkerhuis, by naming our meeting room after him. Jaap’s response was heartwarming, but as modest as he is, he said a broom closet would also be fine.

The #IETF122 Hackathon is halfway through the first day, with a good atmosphere and plenty of discussions and coding underway. The venue is spacious, with daylight, and is working well for us! #IETFHackathon #OpenSource #OpenStandards

The DNSOP WG has two sessions at #IETF122—Monday and Thursday! We’ve got a full agenda with ongoing WG drafts and new work. Check out the agenda and see how you can participate (including remotely) here: datatracker.ietf.org/doc/agenda-1.... Looking forward to seeing you! #DNS #IETF

This weekend, the #IETF122 Hackathon is happening in Bangkok! Over 400 people have registered for the #IETFHackathon, including 50 remote participants! Check out the listed projects or add your own on the Hackathon wiki: wiki.ietf.org/en/meeting/1.... See you all on Saturday and Sunday!

Best job in the world, working at @nlnetlabs.bsky.social!

We need your help! We're making good progress with #XDP support for our #DNS software. However, to properly test it we need access to two metal boxes with 10Gb/s NICs that have XDP driver support, e.g. docs.cilium.io/en/latest/re.... Please contact us if you can help out. 💚

We’re heading to Brussels! 🇧🇪 Our team will be in the heart of Europe this week for a packed schedule of events, and we’d love to connect with you. Whether you're attending the same events or just in the area, don’t hesitate to say hi.

Routinator 0.14.1 is out, fixing CVE-2025-0638, where non-ASCII characters in the file names listed in an #RPKI manifest lead to a crash of Routinator. You should also note CVE-2024-12084, fixing a flaw found in the rsync daemon. Please update both applications. nlnetlabs.nl/news/2025/Ja...

Routinator offered support for #RPKI Autonomous System Provider Authorization (ASPA) as an experimental feature for quite some time. #IETF standardization has now progressed far enough to make #ASPA a core feature in Routinator 0.14.1. #OpenSource #OpenStandards github.com/NLnetLabs/ro...

First blog of year! Why You Should Be Using a Privacy-Centric DNS Service in 2025 www.quad9.net/news/blog/wh... #DNS #privacy #security

2024 has been a pivotal year for us. Our vision for #DNS, our commitment to #rustlang and, in its wake, the influx of new talent, all combined with the support from @sovereign.tech, we’ve been able to make a giant leap forward in realizing our #OpenSource goals. blog.nlnetlabs.nl/domain-found...

We have released NSD 4.11.0. One notable feature is that configuration can be reloaded and evaluated on SIGHUP, when enabled with the new "reload-config" option. Also, #DNS cookie secrets will be reevaluated from config. nlnetlabs.nl/news/2024/De...

Registration for #IETF122 Bangkok (15-21 March 2025) is open! All the details are at: www.ietf.org/meeting/122/

Our #DNS toolkit for #rustlang using our domain crate is nearing completion. We'll offer tools to transform a DNSKEY RR to DS RR, create a #DNSSEC key pair, print out the NSEC3 hash for the given domain name, generate a DNSSEC signed zone, and more. github.com/NLnetLabs/dn...

It’s #IETFHackathon time again at #IETF121! Nearly 50 projects and a room full of enthusiastic participants. For an overview of all the projects, check out the wiki: wiki.ietf.org/en/meeting/1.... And of course, no hackathon is complete without coffee (a must!) and cookies!

We’re happy to announce our investment in @nlnetlabs.bsky.social's domain project, expanding this comprehensive, memory-safe library for building privacy & security-conscious DNS applications. This is another step towards a safer and more resilient internet: www.sovereigntechfund.de/tech/domain
