Yeah. there's a lot of bad networking voodoo out there. I was on the NY State Thruway in recent weeks, and noticed a few things: 1) Don't query their website for an AAAA record, nor attempt to report it to the state. They say "we don't support IPv6" - not understanding sending back a SERVFAIL is bad 2) Don't expect 1.1.1.1 to work, they use that as a HTTPS portal, so you not only get broken IP, but a broken certificate login page 3) Comcast will sometimes reply from a "different" IP than you sent the query if the dns query fails in such a manner. - Jared
