Well, if the server disappears, I'm sure you can guess what happens. You've got to work out how likely that scenario is. It's also possible to have fall-over backup servers. How it's accomplished is turning off the DHCP server on your router, there'll be a configuration option somewhere. Then you install and configure a DNS and DHCP server somewhere on one, or more, of your PCs, and configure them to integrate with each other. Which, like many things, is often harder to explain than actually do (there's quite a few webpages around on the WWW about "local DNS and DHCP serving on Fedora", or Linux in general). Your DHCP server will not only be configured to dole out IPs to your network, it'll also inform those PCs with what addresses to use to get out to the internet through your router (the gateway), etc. PCs connecting to the network will ask to be configured as a broadcast query to anything that listens, and your server will respond. The simple solution would probably be to configure your router's DHCP server to always dole out the same IP to the same machine. Quite a few have a table that lets you enter NIC MACs to be given a certain IP. But this is more limited than running servers on a PC. e.g. You don't often get a chance to manually set up DNS records for a LAN on a router. -- (Currently running FC4, occasionally trying FC5.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
