Today's winner of the amusing hostname prize is 'GE-queer-A.gay.it' aka 'server1-gay-it.it.net', which is what the IP address 151.1.32.3 currently claims to be in SMTP (the first name) and its PTR records (the second name; there is no matching A record).

I do have to wonder what sort of naming scheme gave rise to this. (It has neighbors with different 'serverN' PTRs, so it's not just one machine.)
