I need to used multiple loopback addresses (interfaces) for an

communication, hence better for my purpose.
It doesn't short circuit the network stack, thats why we have the loopback
driver in the first place.
How do I define multiple loopback interfaces?
you can use the ip utility to create dummy network devices on top of your
loopback device, but the better question is - why? Having multiple clients and
servers on a single system doesn't in any way require multiple loopback
interfaces. just have the servers and clients all listen on, and connect to
127.0.0.1, and assign each server a separate port number.

BTW, I'm a newbie to this mailing mailing list. Hopefully this is an
appropriate question?
