I am trying to wrap my head around setting up our external reverse DNS and I just don't get it.  According to our ISP our network block has been delegated to our name servers.  I've tried multiple things and I just can't seem to make it work.

Let say the address range we were provided is  How do I setup Bind 9.3x to handle the reverse DNS?  Here's snippets of my configuration (modified of course).

All of my zones and configs load without error.  But when I try and reverse the ip address I get nothing.

I don't understand the hand off per RFC 2317 and how to setup our DNS.

Any help would be greatly appreciated.


zone "0/" {
        type master;
        file "/var/named/10.11.12.rev";
$TTL    86400
0/   IN      SOA     ns1.example.com infrastructure@example.com. (
                        38400 )
        IN      NS      ns1.example.com.
        IN      NS      ns2.example.com.
20      PTR     email.example.com.
