"The Internet went to multi-label hostnames ~20 years ago.We added ".ARPA" to
all the single label hostnames as partof that process. The only hold over is
"localhost" andthat is implemeted locally, not in the global DNS. No sane TLD
operator can expect "http://tld"; or "user(_at_)tld"to work reliably. I suspect
there are still mail configuationsaround that will re-write "user(_at_)tld" to
user(_at_)tld(_dot_)ARPA(_dot_)Should we be writting a RFC which states that MX
and addressrecords SHOULD NOT be added to the apex of a TLD zone?
Should we be writting a RFC which states that single labelhostnames/mail
domains SHOULD NOT be looked up "as is" inthe DNS?"
Both sound like good ideas to me.
