I'd like to create some access policy by bind and I'm wondering if is it possibile to setup dynamic/parametric lookup answers in bind per-client. Something like:
// Answer to nslookup example.com if($client_ip == '192.168.1.10') return ('18.104.22.168'); else return ('127.0.0.1');
In alternative I could create a secondary bind instance using
-c secondary-bind-config.conf on another interface but I'd like to have just an instance of bind running.
