This extension allows you to display the public IP address.When your browser (the client) connects to an Internet site (the server), the IP address is transmitted in clear and it is therefore possible to display it.
An Internet Protocol (IP) address is a unique number assigned to each device wishing to communicate with the Internet. It mainly has two functions: identifying a network or knowing a location.
The IP address is systematically traced and recorded in the logs or "activity logs" of the remote server.
However, it is possible to use a VPN or a proxy to change your public IP address and no longer be traceable on the internet.
