Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have multiple BIND servers, some are resolvers and some are authorative DNS servers.

When querying the resolvers for reverse pointer records for 10.x.x.x IPs the query fails. I have added these reverse pointer records on the auth DNS servers. Now, as I understand it, I need to tell my BIND resolvers to ask my BIND DNS servers for records relating to this IP range (otherwise they will query the root servers and fail).

How can I configure this?

Thanks you.

You should configure forward zones on your resolvers and point them to your authoritative servers. The configuration may look along the lines of the following example:

// forward queries for 10.0.0.0/24 to the name servers at
// 192.168.1.1 and 192.168.1.2
zone "0.0.10.in-addr.arpa" in {
  type forward;
  forwarders { 192.168.1.1; 192.168.1.2; };
};
