It is very easy to add address(es) to an interface.  From the command
line you could use the "ip" command to manipulate network devices.  You 
can also add routes and bring devices up and down, change their MAC, and 
many other fun things.

ip addr add 1.2.3.4/24 dev eth5
ip addr add 2.3.4.5/16 dev eth5
ip addr add 3.4.5.6/8 dev eth5

You would now have 3 addresses on different width subnets on one network 
device.

Its man page is very terse but gives a very good idea of its power.
