dnsbind is probably more what you want for this.

bind9 is a real pain to set up properly... if you have a need to run a
full DNS server and, say advertise maps to servers in the cloud, or
you just want to know how to do it, all fine.  If you just want your
DNS to be fast and local, dnsmasq is a lot easier to setup, and does
the job with less work.
