[wplug] Multiple Static IP's

[Ken Rambler]

That seems to be the correct answer (or at least one way). I just have
not had to do this so I was unsure, but several resources suggest the
same aliasing method. Thanks to everyone for input!

I thought the traditional way of doing this in Linux was to use IP 
aliases and virtual adapters.

For example:

eth0       ->   192.168.0.1
eth0:0    ->    172.16.0.1
eth0:1    ->    10.0.0.1
 
All of these are the same physical card but this would allow different 
DNS names, IP addresses, and consequently SSL certificates for each 
virtual adapter.  There's more documentation available here:
http://www.faqs.org/docs/linux_network/x-087-2-iface.interface.html

Look for section 5.7.8 at the bottom of the page.
