root.hint and 127.0.0.zone

The root.hint and 127.0.0.zone files are used for a regular name server just as they are used in a caching only name server.  These files will go in the /var/named directory.  You should also edit the /etc/nsswitch.conf as indicated at the bottom of the page. Comments are Blue.


// /var/named/root.hint

;       This file holds the information on root name servers needed to

In the /etc/nsswitch.conf file add a line that says:

 hosts:  files  dns

This says to search the /etc/hosts file and then the DNS server referenced in the /etc/resolv.conf file when trying to resolve names.
