There is an ActivityPub proposal that involves the #DNS.
I have only just discovered it and have not considered it deeply so I am reluctant to make any grand statements. It is not obvious to me why this is useful or better than alternative approaches. It appears to involve the use of TXT RRs, any new de facto use of which makes me skeptical.

I had to migrate my #DNS today, and Hurricane Electric is such a pleasurable return to 90s.
Website obviously designed by a backend engineer. Has only tables and buttons. Buttons work and do things. It's fast. It support features fancy sites do not support. On top of it, free.

I really dislike the "it's always DNS" trope because frequently it's something else, but #Kroger's shit was fucked all day and it was definitely #DNS. I think they have it loosely functional now, though there are so many nested CNAMEs the

Why am I smelling #DNS again :mortysmile:

#DNS trivia, especially for those have ever used the "It was DNS" meme. What is wrong with this (real) dig response and what is the likely cause? AI probably won't help you.

Heute hat die Welt mal wieder gemerkt, wie das so ist, wenn man von US-amerikanischer IT abhängig ist, oder?
Wie hoch ist die Chance, dass die Welt nach diesem zichsten Ausfall von großen Anbietern endlich mal etwas lernt?

It's never a good sign when your Monday morning feed is full of #dns and #aws memes. Monday's eh? 🤷

This is not the first time for #Microsoft #DNS-related problems. As I recall, the first one I remember from 2001 had something to do with their authoritative name servers residing on the same IP4 /24 that had an access or availability problem.
It was a rookie mistake even then, and they were …

This is on the obscure side, but I wouldn't be surprised if some people get bit by this...
If you're using the Perl Net::DNS library for, say a custom #DNS server daemon, once you upgrade to 1.42 or later (Debian 12 had 1.36, Debian 13 has 1.50), your server is probably going to break or mysteriously stop working.

Hey #askfedi one of my family members android device is making these DNS quarries. I can't fine the culprit. I don't see any weird property apps install on it. Any idea who could be doing this?
Edit: I found syncthing is doing this. But why? Why syncthing needs this? And what is stun?

Have you noticed that when the blame #DNS meme starts flying the root is perfectly operational, there is rarely a mention of the big registry operators, BIND, Unbound, Knot, and PowerDNS are absent the conversation, and many who can craft a reasonable dig query are getting responses from local and public resolvers to debug?
Even with all the misconfiguration, added complexity on top of it, a…

On 2025-01-19 there were two "biden" names, bidenlibrary and bidenwhitehouse. Not so unusual. Associated names for Obama and Trump were also there and remain still. These are exec branch names but the agency responsible for them is the National Archives and Records Administration (NARA).
As of today, there are four additional "trump" labels in the …
