Disable bind on public interface

If you need to disable listening on an interface for DNS on a CSN, you may add the "listen-on" option in the options section in /etc/named.conf and issue a:

 service named restart

This is what a sample options section looks like:

options { directory "/var/named"; forwarders {

172.17.254.254; }; listen-on { 10.5.0.5; }; };
