There is a nice set of links with respect to DNS 'For Sale' records (see RFC10023). It is maintained by @marcodavids of @sidnlabs. rfc10023.nl/

.@sidnlabs publiceert voortaan dagelijks open #RSSAC002-statistieken over het #DNS-verkeer naar de .nl-nameservers. Onderzoekers en operators krijgen daarmee inzicht in o.m. queryvolumes, responscodes en unieke bronnen, via openbaar beschikbare datasets. sidnlabs.nl/nieuws-en-blogs/…

In case you missed it: we run a pretty solid public NTP/NTS service named TimeNL - it does a little Rough time too. 🕓 Check it out: nts.time.nl and time.nl/

This is the kind of infrastructure I love. No walled garden. No special integration. Just an open DNS record any agent can read. Small building blocks like this are how the internet actually changes.

DNS GETS A “FOR SALE” SIGN FOR DOMAIN NAMES — A new DNS convention lets domain owners hang a machine-readable for-sale sign on registered names, revealing purchase opportunities that domain searches often hide. by Marco Davids circleid.com/posts/a-domain-…

A Domain Is Registered. But Is It Really Unavailable?

RFC 10023 standardizes a DNS TXT record that lets domain holders signal a registered name is for sale, giving registrars, marketplaces, brokers and search tools a machine-readable way to distinguish...

💥 Put a “For Sale” sign in DNS! 🚀 📜 RFC 10023 defines a simple, open convention for domain owners to signal that a domain name is for sale - in a way that both humans and machines can understand. 👉 rfc10023.nl #DNS #IETF #RFC10023 #DomainNames

Voor #TimeNL, onze publieke tijdsynchronisatiedienst, willen we onze afhankelijkheid van Global Navigation Satellite Systems verminderen. Daarom introduceerde @sidnlabs onlangs 2 nieuwe servers die hun tijd rechtstreeks via glasvezel betrekken van de bron. sidnlabs.nl/nieuws-en-blogs/…

Met behulp van #BGP kunnen autonome systemen via BGP-updateberichten bereikbaarheidsinformatie uitwisselen met hun 'buren'. Onderzoek laat zien dat hierbij veel ruis ontstaat. We onderzochten 80 miljard BGP-updates om meer zicht op die ruis te krijgen. sidnlabs.nl/nieuws-en-blogs/…
