Add Virtual Network Interface to Ethernet Card

Want your single physical network adapter to have multiple addresses?  In Linux, it is very easy to add new addresses to your existing card, just use the ifconfig command:

$ sudo ifconfig eth1:0 192.168.100.252

(eth1 is the physical adapter, 0 is the first virtual adaptor)
