Setting up nameservers on RedHat Linux 7.1 ???

[Kevin Darcy]

Unless you have 2 servers available to provide DNS, you need to get someone
else to be your slave. Under no circumstances should you delegate your domain
to two different addresses of the same box -- that would defeat the whole point
of the 2-nameserver requirement, which is to provide redundancy!

Regardless of how you do things, though, the "www" name can just be an alias to
some other name, or you can have multiple names resolving to the same
IP address. You don't need a unique address for every name in your DNS domain.
