There are multiple ways to find out which public IP address you are using at any given point. But the easiest way is to go to one of the many websites that are set up specifically to show you what your IP is, such as whatismyipaddress.com or ipchicken.com. If you are using the Chrome browser, Firefox browser or an updated version of Internet Explorer, you can also do a Google search for “my ip address” and it will list your public IP address for you at the top of the search results!
