Having a name is one thing; being able to find out that name with reverse
DNS is another. So if ns.example.com is 192.168.47.11 but there's no PTR
record for 11.47.168.192.in-addr.arpa, you have a name server with a name
but one that you can't use reverse DNS to look up the name for.
Or what do you mean with "an authoritative name" -- does that mean a name
that reverses to itself?
