  IP masquerading and IP aliasing are different.  In IP masquerading, one 
machine connects to the world via some kind of connection.  It then 
allows the other hosts on its own network to use it as a router without 
subnetting.  I haven't really looked at it, but I'd guess that it just 
uses a set of higher outgoing ports on the "router" to connect to the 
remote computer, and then sends packets that arrive on those higher ports 
back to the original sender.  There's something similar available for 
windows as well.
