Smaller, faster: NSD's refactored RDATA storage and compile time memory reduction options On the 4th of December, NSD 4.14.0 was released with refactored RDATA storage, reducing the memory footprint of NSD. In this post we'll show the effect of this refactoring, what sort of zones benefit ...

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...

NLnet Labs Community

We now have a forum for Roto and the other @nlnetlabs.bsky.social projects, which should make it easier to ask questions and start discussions! You can also interact with it via email if you prefer.

Check it out at community.nlnetlabs.nl!

We are not NLnet. We make open source software ourselves, like Unbound and Routinator

I collaborated with @cirw.in at EuroRust to make a Zed extension for Roto! It's based on the tree-sitter grammar and supports syntax highlighting and generating an outline. It can be installed via Zed's regular extension manager.

Thanks @cirw.in!

News - End-of-Life Roadmap for OpenDNSSEC OpenDNSSEC will reach end of life in two years, October 2027.

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.

We are not NLnet.nl. We develop #OpenSource software ourselves and are not affiliated with the foundation that funds projects. We do think they are awesome. 😊

And as always, I forgot the hashtags. How do feeds work again over here?

Anyways, we did a Roto release! Check out this thread for the highlights.

Forgot to tag @nlnetlabs.bsky.social properly! Darn you Bluesky let me edit my posts!

Yes, we’ve got some shared history: NLnet Labs was started by board members of NLnet. But we’ve always been independent. And, as the saying goes: NLnet Labs writes code, NLnet writes checks.

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.

Thanks to Xiang Li for reporting!

Need a fast, safe scripting language for your Rust app? Terts Diepraam and the team at @nlnetlabs.bsky.social couldn’t find one that fit. So they built their own. It’s called Roto. And you’ll be hearing all about it at #EuroRust25. 👇🏼

We updated DNS-over-QUIC in Unbound #DNS resolver to use the latest release of ngtcp2, version 1.13.0. It now also supports OpenSSL 3.5.0.

In addition, this change now calls the new performance increase init for the ngtcp2 crypto library. #DoQ #OpenSource github.com/NLnetLabs/un...

We are not the NLnet Foundation/ NGI Zero. We don’t believe they are on Bluesky.

We spent 2024 working on 'domain', our #DNS library for #Rust, as part of a grant from the Sovereign Tech Agency. As this work finished up and we approached 2025, we took a closer look at the foundations and realized the best way towards a more ergonomic and efficient 'domain' was to rework them.

Overhauling Domain By Arya K. Previously, we discussed the massive development our domain library underwent over 2024. However, the project has been around much, much longer than that – the very first commit was made a...

Five months, several iterations, and tens of thousands of lines of code later, we're ecstatic to announce the release of domain v0.11.0. We'm so proud of the team, and Arya in particular. You can read about her experiences in this article. #opensource #rustlang blog.nlnetlabs.nl/overhauling-...
