Show me the rfc which states that rudd.cc is not a fully qualified 
domain name.

For example, RFC 819 says that a name is partially qualified if it omits 
common ancestors between two names (ancestors starting with the root 
domain up to their common sub-domains).  Otherwise it is fully qualified.

Thus, rudd.cc is fully qualified because it does not omit any ancestors. 
  It contains the full name of the host, all the way to the root domain. 
  (well, ok. "rudd.cc." is fully qualified; "rudd.cc" omits the root 
domain ... but aside from that one quirk, show me an RFC which states 
that it's not a FQDN)
