Most "better" DHCP servers allow a sort of "static" DHCP where you
statically set the IP of each client at the DHCP server. The DHCP
server, on recieving a DHCP request, checks the requests MAC, cross
references it to it's internal list, and hands out the static IP.

The benefit is that while everything is static, everything can be
changed at only one spot, the DHCP server.
