BIND can be set up using Red Hat's BIND Configuration tool, which configures the DNS server itself and can also create and edit the zone files served.
Alternatively, the server can be set up manually by modifying named.conf and creating the zone files in /var/named/.
After changes are made, the named service must be restarted for the changes to take effect (using Red Hat's Services config tool or the service command).
Save your zone files to /var/named/ to have them served by BIND.
