Generally a cable modem acts as a bridge and just passes traffic
through without an address change so if your computer is attached
directly to the cable modem the numbers you get by typing
ipconfig /all (Windows) are the real numbers accessable from
outside.
If you have your own router between the cable modem and your
computer you can get the real addresses by loging into it and
checking the WAN status. If you have an internal router that
gives your local network a private address range (like 192.168.1.n)
you'll need to program a port forward to your computer's IP
and address the router's WAN address from the outside.
If your cable modem is actually a router, giving you private addresses
on the LAN, then you need information from the service provider.
