Adding to my previous post.

I am running an apache web server on my windows xp machine, just for
development purposes. My computer does not serve pages over the internet.

The machine is running Windows xp professional behind a router with a static
IP address. I also have a domain name and the DNS is run from my ISP, but
there is a server on my network which can run DNS (static IPs).

I would just like to run some virtual hosts on my local machine for
development purposes. I am not interested in anyone accessing these servers
from the public, at all.

I have been reading a lot about Windows loopback, ip aliases, and such. The
apache site tells how to set up IP-based virtual hosts, but I am not sure
how to set up additional IPs on this computer. can anyone supply a simple
answer or more good references I can add to my collection?

Thanks again.
