[CentOS] Bind - built in root hints?

[Bry8 Star]

The named.cache / root hints just updated on jan 3 2013 after jun 8
2011.
I'm not 100% sure but i think many centos/rhel boxes are still using
that 2011 hint.
So before rhel/centos releases/updates their bind/hint file/bin, or
users who do not want to update hint/bind portion specifically via
yum, for such type of users, to use the latest hint file, i think
the existing hint file & its location would help to place the latest
hint file.
