How to Find Someone's IP Address

An IP address is the online pointer to a person's computer. It is recorded on Web servers when you're on the Internet. You can hide your actual IP address with a proxy, however, so the proxy's IP address displays instead of yours. Finding someone's IP address is tricky, but not impossible to do. You'll need to get the person to interact with you in some way to get the IP address. One of the easiest ways is through email, which saves the computer information with the message.
