If this is a normal home network, it is entirely possible that the
target machine is using DHCP. The DHCP servers on many home routers are
not always set up to give the same IPs to the same MAC addrs. So: Go
to the target machine and find out what its IP and MAC
are--"/sbin/ifconfig" from the command line will show that info. Then
set up your router such that it will always give out 192.168.0.4 to that
MAC.
Many home routers also act as tiny caching DNS servers by default.
Some of these are smart enough so that you can associate names with IPs
in the local LAN, so that you can "rsync /path/to/stuff/
machine1:/backups/stuff/" instead of 192.168.0.4:/backups/stuff/ .
