By RFC 952, there were no dotless names in HOSTS.TXT, even though the
grammar allowed it.

i'd really like to see those as A.ROOT-SERVERS, B.ROOT-SERVERS, etc,
where ROOT-SERVERS. was an empty non-terminal (not a delegation point).
so, in-zone, but not dotless. because most of my daily-use tools won't
let me ping "A" or "A." since they are both treated as local names (to
be found in YP/NIS or /etc/hosts or the Windows "hosts" file), and i
like pinging root name servers.
