    For small networks, I recommend using dnsmasq. It's a combined DHCP server and DNS server/proxy intended for use on a masquerading gateway that can run nearly without any configuration. Add your mac addresses to /etc/ethers for fixed IP adresses, add your hostnames to /etc/hosts, finito. There is no need to fiddle with to big servers (bind and ISC dhcpd). I use it on my (heavily modified) WRT54G with about 10 to 20 systems without any problems.

    Actually, DHCP is especially useful on a small network, as you can setup the DHCP server to assign addresses to specific MAC addresses instead of manually configuring the details in the OS.

    This is handy if you continually resinstall operating systems on a box, and have gotten used to accessing it via a specific IP address, or whatever.

    Besides, by using DHCP, you can add new hosts without doing a thing. This means your friends can come over and plug their shit in without problems, and your network will be filled with with trojans in no time.
