IP stands for Internet Protocol address that functions as a numerical label for each workstation from within a network.
IPs are used for identifying the location of the computer, and consequently restrict or allow access to various services.
Applications that hide IPs replace the real address with a fake one that will make the computer seem like it is located in another country.
This way, privacy is ensured when surfing the Internet and blocked websites become accessible.
Some of the applications that allow IP hiding offer users the possibility to choose the new IP, but most of them automatically replace the address with an available one.
