Would an internal caching nameserver still be a good idea? I have a small site; 4 FreeBSD machines, one of which is the gateway/router and one of which is the server, a test box and a workstation, also a Sparcstation5/Solaris box.

I understand the implications of this setup, however, my IP hasn't changed once in 2 years. If it does, I have ddclient checking periodically with ZoneEdit to update the IP. Will this still take [up to] 72 hours to propagate, as with any name updates? > Another example is my reverse DNS does not always work, and > guess what?

I know that I sometimes complicate things more than they need to be in my own mind...
