According to all known laws of DNS, there is no way a fedi instance could be hosted on an .ARPA domain.

Even if you get ahold of a domain like this, it should only be used for PTR records - right?

The instance, of course, federates anyway - because DNS doesn't care what humans think is impossible.

@loke @domi A really, really bad idea. As someone who worked at the first site on the early ARPANET at UCLA and worked on the original ARPANET protocols and continuously going forward from then, I assure you that doing this will cause you nothing but grief down the line. You can play games with DNS but eventually you'll get bitten. Trust me on this.

@lauren @loke @domi I've run fairly large authoritative dns deployment, I've hacked in the protocol in various ways.

The only concern is if the block allocation is pulled, but this a RIR/LIR concern.

There is nothing in the protocol that would consider this a violation. At the end of the day, this is straight up NS delegation. Is this unusual? yes. Is this humanly possible to remember an ipv6 block allocation? No, not in a large scale, this is the reason for DNS in the first place, but that's it?

@kkarhan @baloo @lauren @loke @domi speaking of…”unconventional” TLDs for individuals to have, back near the turn of the century (2000-01 or so i think), I knew of someone who had a .edu domain for their personal website. I’m not entirely sure how they pulled it off, I guess the eligibility criteria were enforced mostly by the honor system at the time that they registered it

@maia @kkarhan @lauren @loke @domi edu registration was just a single person maintaining it for a very long time. And you'd email them to have a domain on it.

They had a bunch of made-up rules, like the length was to be kept under 8 chars.

My partner works at a museum that would have violated that rule, when they applied in the early 90s. They just waived the rule for them.

Yeah, honor-system, mild enforcement, or just feeling based.

@lauren @loke @domi that’s funny, you’re taking the internet seriously, you’re taking internet engineering seriously. lol. this isn’t even against the rules. these domains are delegated like anything else, they just often don’t point to AAAA/A records. rfcs are guidelines, not rules. rfcs just say what your PTR record has to be, not what your AAAA record can be.

did you know @ruhrscholz played videos over TXT records before? it broke powerdns, but they even accepted the patches to fix it

@filmroellchen @domi @loke @ruhrscholz Where did I say anything about rules? I never mentioned the word. All I said is that depending on these kinds of "tricks" is looking for trouble. And I stand by that. I've had to help a large number of people undo the messes they've created over the years trying to be "creative" in DNS records. But hey, pick your poison.

@lauren @loke @domi grief in what way? the worst thing that can happen is loosing access to the rDNS for that IP range (and thus maybe the fei instance). If your source is "trust me on this" I'd love to hear some specifics on the terrible things that can (or apparently will) happen

@merlin I'm also curious since I've played around a lot with rDNS and the only thing I'm coming up with that might be problematic is just being a pain in the ass hostname for humans.

@BalooUriza @merlin

This will break some DNS management frameworks. Including a long-retired one I wrote. ;-)

The bugs are due to the DNS management system developers' mistaken assumptions about what's allowed to have what kinds of records.

I learned better the first time when I used DNS for data transport and authN in a wifi captive portal 25 years ago. I will (probably ;-) ) continue to learn better for the rest of my career.

@merlin @lauren @loke @domi you may stumble upon a crappy appliance that would forbid requests to ip6.arpa....

Example: in France the Free operator router refuses to serve DNS answer when the answer Is an RFC1918 IP...

@lauren @domi I'm pretty sure the owner of the instance knows as well. In the description it is mentioned that it'll only be up for a month.

I was just surprised it worked. But of course, thinking about how DNS works, it makes sense. Good idea? Absolutely not. But it's a cool experiment that teaches us a bit about DNS I think.

Written by Lauren Weinstein on 2025-01-30 at 06:16

@loke @domi Sure, experimentation can be fine so long as it is not going to negatively impact other systems. But it's always useful to keep in mind the distinction between experimental and production configurations. I will add that "unusual" domain configurations stand a very high chance of being blocked or tagged as problematic in the long run. And once you get on those block lists, getting off again can be, shall we say, challenging, because there is often an assumption -- not without considerable merit -- that oddball configurations and "creepy" DNS entries are attempting to bypass spam/phishing/malware blocking systems and filters -- which is not infrequently the case.
