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.
@domi this is amazing.
@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.
