That depends...
- Is the other server going to host a zone named
dynamichost1.example.org? Or will it host example.org?
- What do you want your server to send in response to iterative
queries? An answer, or a referral?
If the parameters are correct, you could handle this with a delegation
and (if necessary) a forward zone. For example:
In the zone file:
dynamichost1 IN NS otherserver.
In named.conf:
zone "dynamichost1.example.org" {
type forward;
forwarders { ip-of-otherserver; };
};
