Multihome in XP... DHCP?

I know that you can configure multiple IP addresses on a single NIC in
Windows XP, but is it possible to have XP lease multiple dynamic IP
addresses on the same interface?
 
I don't think so. However, you may have one dynamic IP address plus multiple static IP addresses.

Amazing, my old sig file which had suddenly vanished into the matrix
reappeared at the bottom of this post, Least it's the first tine I've read my
correspondence that far before writing anything.

I've not only wondered about this too as you have both an internal and an
external IP address you can configure, but I've gotten myself even more
confused about it as to how and what role proxy servers could play in this.
OK, if you are lashed down to a single external IP address by your ISP is it
possible to use possible to set up several different internal IP addresses
and handle simultaneous feeds through them? Would the proxy servers help
handle returns to the IP addresses of origin?
 
Default behavior in Windows is for a single NIC to have either a dynamically
or a statically assigned IP address, but not both at the same time. A single
NIC may have more than one statically assigned IP address which may be on
more than one network. If your ISP issues you a single IP address for your
network, you can give that address to a router/firewall which can then
dynamically assign addresses to your internal network. (You might also choose
to assign static IP addresses within your internal network.) Your router will
help ensure that traffic gets to the right place. IP address ranges used for
your internal network should be non-routable (like 192.168.1.x).

A proxy server has a totally different purpose. It is designed to store
frequently requested web content to make it quickly available in your
browser.
