4.5.1. The reverse zone isn't delegated.

When you ask a service provider for a network-address range and a domain name the domain name is normally delegated as a matter of course. A delegation is the glue NS record that helps you get from one nameserver to another as explained in the dry theory section above. You read that, right? If your reverse zone dosn't work go back and read it. Now.

The reverse zone also needs to be delegated. If you got the 192.168.196 net with the linux.bogus domain from your provider they need to put NS records in for your reverse zone as well as for your forward zone. If you follow the chain from in-addr.arpa and up to your net you will probably find a break in the chain. Most probably at your service provider. Having found the break in the chain contact your service-provider and ask them to correct the error.
