HI 

   My ISP has finally given me control of my reverse dns. I been told it had
something to do with classless delegation. So i look around the net to find
help about it.

here is a copy of my reverse dns zone

$TTL 86400

@       IN      SOA     @       davidr.skyforge.net. (
                        3; serial
                        28800; refresh
                        7200; retry
                        604800; expire
                        86400; ttl
                        )


        IN      NS      ns1.skyforge.net.

175.199.204.217.in-addr.arpa.   IN      PTR     infa.skyforge.net.


the stuff from named.conf is

zone "28/160.199.204.217.in-addr.arpa " {
      type master;
      file "/etc/namedb/primary/160.199.204.217.in-addr.arpa.zone";
};

I changed the serial as i made changes to the zone. I have been getting
these errors. I dont understand the first one, but i dont think it is
important. But the second one doesnt change even if I changed the serial to
1000 or 2 or etc...

/etc/namedb/primary/160.199.204.217.in-addr.arpa.zone): no SOA RR found

Jun 10 13:55:07 spaceport named[93608]: Ready to answer queries.

Also when i use nslookup on the server, it doesnt work the ip ?

any ideas why? and any help would be very helpful
