[CentOS] DNS Server Recommendations

I recommend a highly secured master that is not queried by any clients
(preferably in a network/vlan your clients can't even access)... then
configure one-way zone transfers to 2 or more slave servers which you
configure your clients to point to. Maintain your zone files in rcs of some
sort... For IP control/delegation and DNS control/delegation I recommend IP

Of course bind is the 800lb gorilla in the DNS world... don't even think
about putting DNS on windows.

I don't recommend any front ends being that a few hours well spent reading
the docs and man pages will make you a dns expert in no time. Bind is very
easy to learn and shouldn't take longer than an afternoon at best.
