In this tutorial, we learn how to find someone's IP address. First, log into What's their IP. Once you open this, enter your email and click the links that can be sent to your friends. Once they click on these links, the website will email you that person's IP address. You can now look this IP up to see the exact location of that person. There are several different options of pages that can be sent to your friends if you want to track their IP addresses. There is also a page that can be sent to them that tells them their IP was just emailed to you!
