DNS notes: sub domain delegation with global forwarders

When you have global forwarders configured in your named configuration, sub domain delegation does not work as expected. Lookup's for sub domains of zones (even if you are authoritative) get forwarded to forwarders.

To disable forwarders for the zones, you are authoritative for - you need to add a null forwarders list in to your zone configuration

zone "mydomian.test" in {

    type master;

    file "master/named.test";

    allow-update { "localhost"; };

    forwarders { }; 

};
