RE: Setting up DNS

[Scott Stone <SStone@example.com>]

yes, that could be a potential problem.. when those machines attempt to
access other machines, the other machines may have trouble if they cannot
reverse-resolve the IP addresses of the clients talking to them.

Thanks for the info!

However there are some machines that I don't want to be addressable by name,

just by IP. Will it cause a problem if I don't list those particular 
machines?
