That's call a Virtual Ethernet Interface but requires three sources to feed the virtual addresses, eg:

--- 192.168.1.x network ------+
--- 172.16.10.x network ---+  |  
--- 10.101.23.x network -+ |  |
                         | |  |
                     common switch ---- [B]systemX[/B] with Virtual Interfaces

Then systemX can have one NIC which has a real ip address on (say) the 192.168.1 net,
and virtual addresses for the 172.16.10 and 10.101.23 net

The source networks could just as easily be public ISP connections thru separate modems
(which would require 3x DSL lines and modems for example).
