You can create aliases doing 'ifconfig ethx:y', where x is the main
interface number, and y starts at zero and increments for each interface.

With Advanced Routing in your kernel, you can assign an entire subnet to
your interface with:

ip addr add n.n.n.n/yy brd + dev eth0 label eth0:Aliases

..which takes all of the IP's in n.n.n.n/yy, assigns them to your
interface with the standard broadcast address, and calls the alias
'eth0:Aliases'.
