[SWLUG] hopefully easy question: naming machines on a tiny network

[Mark Summerfield]

Hi,

I have a BT Voyager router (a few years old) & 3 machines. The router
always gives the machines the IP addresses 192.168.1.2, 192.168.1.3, and
192.168.1.4. But not always the same number to the same machine. Is it
possible to tie each IP address to a particular machine (and ideally to
use names)? Two machines run Linux the other Mac OS X.

I am not terribly good at sysadmin as you can guess...

Thanks!
