The latter would seem to be avoidable by making sure that *DNS resolution of bare TLDs always returns NXDOMAIN*. Is that a requirement for a TLD?No. In fact, a TLD lookup that returned NXDOMAIN would be utterly broken since that would mean the TLD had no SOA, no NS, and no subdomains. Perhaps you're confusing it with NOERROR.
No, I was confusing you for someone who understood -- as everyone else here seems to have -- that I meant "querying for an A, AAAA, or MX record".
If it isn't, does anyone know of any domains dumb enough to actual return something for a lookup on the bare TLD?Yes. If you'd read RFC 7085, you'd already know which ones do. There have been A and MX records at TLDs nearly as long as there have been TLDs.
And this is *why* I assumed you knew that, since the RFC is yours, and makes precisely that distinction. Cheers, -- jra -- Jay R.
