static names with dynamic ip's
I have a local network with two box's running fedora core 2 and roommates mac running os X, all behind a router with a dns server and a cable connection that is also a dynamic ip. I would like to reference the file server by name in my fstab config files since the ip address change occasionally. I have thought about using static IP behind the router, but I don't want to intrude on my roommates connection (and I want to learn how to figure this out). How would I go about setting this up? Something to where my fstab file would have "fileserver:/sharedfiles' instead of an ip. Already looked at bind and named possibilities, but its not clear to me if that can even solve the problem. Where should I go with this? What are my options?
