If you are using BIND (Named) you should have something like this:
--------------------------------------------------
view internal {
match-clients { lan_hosts; }; # match hosts in acl "lan_hosts"
recursion yes; # allow local recursive queries
notify no; # disable AA notifies
// prime the server with knowledge of the root servers
zone "." {
type hint;
file "/etc/db.cache";
};
---------------------------------------------------
And the db.cache file stores the root servers list:
---------------------------------------------------
; This file holds the information on root name servers needed to
; initialize cache of Internet domain name servers
; (e.g. reference this file in the "cache . <file>"
; configuration file of BIND domain name servers).
;
; This file is made available by InterNIC
; under anonymous FTP as
; file /domain/named.root
; on server FTP.INTERNIC.NET
; -OR- RS.INTERNIC.NET
;
; last update: Dec 12, 2008
; related version of root zone: 2008121200
;
