Too few sampled comments (4) to say how often HN recommends it.?

Why HN links it

HN readers link SIDN Labs, the R&D arm of the .nl registry, for its DNS and IPv6 work: an IPv6-only network experiment, a proposed DNS signal for domains that are for sale, and a related DNS resolution project.

Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

SIDN Labs is het onderzoeksteam van SIDN. Wij doen toegepast onderzoek voor een veiligere en weerbaardere internetinfrastructuur.

What Hacker News says?

  1. This is very very similar to something developed by SIDN labs called "DNS Resolution Required", you can read the blog post here: https://www.sidnlabs.nl/en/news-and-blogs/dns-resolution-req...

  3. My former colleague Marco Davids from SIDN Labs (the R&D department at the .nl TLD operator) did an experiment in 2021 where he actively disabled IPv4 support on all components in his test network, even disabling the complete IPv4 stack in the FreeBSD kernel (not possible on Linux, at least not at the time). So far, his test is the only thing I know of that came close to an authentic simulation of an IPv6-only world…

  5. I work for SIDN, the ccTLD registry for .nl. Around 2022, we came up with an idea together with some of our registrars: to add a "for sale" button to the WHOIS page for domain names that are for sale. We soon realised that the underlying method could be useful beyond .nl as well. So at SIDN Labs, we decided to turn the idea into an RFC and take it through the IETF process. https://www.sidnlabs.nl/en/news-and-blogs/a…
