Multiple DNS server configuration

It is possible for an organization to have many internal DNS servers serving different domains. Assume the domains to be example.com and example.org. Now if a client requests example.com DNS server for example.org address resolution then the request may be resolved as a public request, because example.com server will treat example.org same as yahoo.com or google.co.in. To ensure that such requests also get resolved locally both example.com and example.org servers should have both example.org and example.com zones. Now example.com server should have following entry in its 'named.conf' file:

        zone "example.org." {
                type forward;
                forwarders { <IP>; };
        };

where <IP> should be IP address of example.org DNS server which would resolve all example.org requests.
