We have the need to set up a CentOS 5.5 server to act as a DNS Caching server to do lookups. This server will not provide any zone hosting. It is simply so that we do not have to rely on our ISPs DNS servers for our client systems. We would however want to make sure that only that clients within our IP ranges are allowed to use the server for DNS lookups.
Does anyone have an easy HowTo? I have searched and foudn some references but I just cant seem to get things working in the most basic of scenarios.
