IP2 is a small program that you can use to determine your IP addresses - both WAN and LAN. IP2 is a small utility that you can use to determine your IP addresses - both WAN and LAN.

What this means is that along with showing you the traditional IP address that your computer is using in its local environment (e.g. a LAN) it will also show you what your IP address is from the perspective of an "outsider" on the Internet.

This is in contrast to the many tools and utilities available on the Internet that simply return the LAN address, which is useless if somebody on the Internet needs to connect to your computer.

Your WAN and LAN IP addresses may be the same if you are directly accessing the Internet with something like a dialup modem or a cable modem without a hardware NAT router.

However, if you are using some kind of hardware router or firewall as your gateway to the Internet, your computer will most likely have been assigned a "non-routable" IP address such as or for example. In this situation there is no easy way to find out what your true Internet IP address is. This is where IP2 comes into play.
