Addresses ending with zero or 255 (x.y.z.0 and x.y.z.255) are generally regarded as special purpose addresses, and machines would normally be assigned addresses from 1 to 254 as the last quad. It's not a hard and fast rule, there are exceptions. But some things make assumptions, and get their knickers in a twist if you try to do otherwise. There's two conventions of using the .1 or .254 address for your router/gateway, but that's just a convention, and about the only thing that insisted on one of them was the *old* Windows internet connection sharing, that insisted on using 192.168.0.1 for the gateway PC. > Also the machine's netmask is 255.255.255.0 and the netmask of the > server should it be 255.255.255.0 or 255.255.255.254 or other thing? If everything is actually on the same subnet (e.g, they're wired together through a switch or router, and they can all connect to each other without having to go through a gateway) then they should all have the same netmask. For the average home network, using 192.168.x.y addressing, then the 255.255.255.0 netmask suffices. If there are separate physical networks, or you have some need to carve up how you're using it, then you can use more restrictive netmasks, and you may have to, for those networks to work (they need to know the boundary between the same network and the outside network, so they can make connections to the outside one through the gateway between them). I would suggest that whatever PC you're running the DHCP server on should have a fixed IP address, and for that to be fixed in your network configuration, not trying to get the DHCP server to set its own IP address. This, probably, also means ensuring that the NetworkManager service is turned off, and the older network service is used. My DHCP server still runs on a Fedora Core 4 box, and I have no parameters set into it for what interface it listens to, there's only one network interface on the box. My working /etc/dhcp.conf file is below, with example.com being used as an example domain name.
