Just to be clear, this is no special magic here, this is only because you have the PTR record for 216.81.209.221resolving to the hostname "nnepa221.nnepa.com". Whatever the reverse hostname is should resolve in the forward zone to the same IP address. -Kevin Todd Richards wrote: > Hmmm, I just switched the DNS to a new host, but don't recall having > that before.
