No, /etc/resolv.conf is for the configuration of the DNS *client*. For
the configuration of the DNS *server* (BIND), the easiest solution is
to have two separate machines (they can be virtual machines). If you
have them, install BIND on both, configure with "recursion no;" on the
authoritative name server and with "recursion yes;" on the caching
server (which should not be reachable from the outside, it can even
have a private IP address).

If you have only one machine, tell it, it will be a bit more
complicated, with views
