IP2 Download
IP2 is a small program 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 you computer is using in it's 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.
