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.
