Reverse Name Resolution Zone File

[Mark Andrews]

The zone is still delegated but the CNAME records that map the well
known reverse names to the actual names holding the PTR records are
not present in 233.202.162.in-addr.arpa.  This needs to be fixed
by AT&T.

P.S.  there is no point in two NS records if there is only one
machine.
