Which brings up a question can a TLD be used like a domain name?
not just http://microsoft/ but bill(_dot_)gate(_at_)microsoft will likely to
fail to.

The Internet went to multi-label hostnames ~20 years ago.
We added ".ARPA" to all the single label hostnames as part
of that process. The only hold over is "localhost" and
that 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 configuations
around that will re-write "user(_at_)tld" to "user(_at_)tld(_dot_)ARPA".
Should we be writting a RFC which states that MX and address
records SHOULD NOT be added to the apex of a TLD zone?
Should we be writting a RFC which states that single label
hostnames/mail domains SHOULD NOT be looked up "as is" in
the DNS?
