The nameserver which it is checking:
(1) is recursive (i.e. it is configured to act as a caching server), and
(2) does not have an authoritative entry for
      1.0.0.127.in-addr.arpa.

In other words:

# dig  at omega.eomw.net. 1.0.0.127.in-addr.arpa. ptr

should return an authoritative PTR record. It doesn't.

In FreeBSD's /etc/namedb/named.conf there is

zone "0.0.127.IN-ADDR.ARPA" {
        type master;
        file "localhost.rev";
};

and you do 'cd /etc/namedb; make localhost.rev' to create that file.

Your other option is to turn off recursion on omega.eomw.net altogether (as
long as you don't have any clients using it as their local DNS cache)

Regards,

Brian.
