When you connect to the Internet from a computer, smartphone, or tablet, your Internet provider automatically provides you with an IP address. This IP address is used to identify you. Your Internet Service Provider (ISP) can communicate this to the law enforcement authorities if necessary.
The IP address may be fixed or dynamic. Some Internet service providers give a fixed IP address to their clients and others make it dynamic, ie this IP address can change on each connection.
An IP address consists of 4 numbers separated by points from 0 to 255, which is called an IP address V4 (4 numbers). For some years now, the IP address has been V6 which does not consist of 4 numbers like the IP V4, but which is different.
The V6 IP address has been set up so that it is not saturated with IP V4 distribution. In a few years, we will no longer talk about IP V4, but IP V6.
My IP Tools gives you the possibility to know your IP address, geolocate it and obtain also additional information free of charge and unlimited.
