Finding a Remote IP

[Ronald Saa]

Hi All,
I have 2 computers that can VNC each other after they go online via
IE6.
Of course I have to email the Server's IP to the Client.

But I also know how to connect them by Dial-up networking without using
IE6.,
which means no one has to be at the Server side.

Heres my question:
After the connection is made via Dial-Up Networking, 
how do I find the Server's newly assigned IP address.

I can understand why this may be impossible before connecting,
but after a Dial-up Connection is made, 
I think someone out there must know of a way.
