This page allows you to find out what IP address, location, and ISP are seen by the online resources you are accessing. This is useful in the process of setting up a proxy when you are not yet sure if the user data has changed.
Not only online resources can find out the IP address, but also intruders. A crafty hacker can easily get to the user’s confidential information with this data. Therefore, it is very important to check your privacy before visiting a dubious online resource.
