Reverse Delegation - Help

[Tim Cropper]

I'm running bind 8.2.3 and have requested reverse delegation from my provider.

I'm having problems getting reverse lookups working properly. Any help is 
appreciated.

Queries to my primary ns from the  ns host result in a listing of root name 
servers. I should be authoritative for this...

nslookup 208.190.133.161 208.190.133.161
Authoritative answers can be found from:
(root)  nameserver = F.ROOT-SERVERS.NET
(root)  nameserver = B.ROOT-SERVERS.NET
(root)  nameserver = J.ROOT-SERVERS.NET
...


Queries to my secondary ns are shown below - I don't know if the alias 
listing is normal...

nslookup 208.190.133.161 ns1.swbell.net
Server:  ns1.swbell.net
Address:  151.164.1.1

Name:    unity.apfa.org
Address:  208.190.133.161
Aliases:  161.133.190.208.in-addr.arpa


CUT <<< from named.conf >>>
zone "160.133.190.208.in-addr.arpa" in {
   type master;
   notify yes;
   allow-query { any; };
   file "db.208.190.133";
   allow-transfer { 151.164.1.1;  151.164.1.7; };
};



<<< db.208.190.133 >>>
$TTL 4H
@        IN    SOA  apfa.org. hostmaster.apfa.org. (
                        2001062003 ; serial
                        24H     ; refresh
                        2H      ; retry
                        1W      ; expire
                        1H)     ; default_ttl

                IN NS  unity.apfa.org.
                IN NS  ns1.swbell.net.
                IN NS  ns2.swbell.net.
