I've been looking a simplest way to create and secure DNS server on a chroot'ed environment for my private network. and I found this good documentation link.
This guide will show you how to get DNS working on
your Debian server using BIND 9. I will show you how to setup the
network interface, and how to maximize security by running BIND 9 inside
a chroot environment. You will need to register a domain name so there will be no conflicts between internet domains and the domain(s) used on your LAN.
