Erm, if you want to run a www server, the only relevant IP is the one on your 
box.  If you're getting a routable IP, then it should be visible on the 
internet, though it'll probably change from time to time because of the DHCP.

If you still want to work out what the IP address of your router is, try doing a 
traceroute to something outside, say:

traceroute www.google.com

That should list the IP of the router as the first hop.
