IP address also referred to as an IP address. It is the identification number of a computer, other devices connecting to the network (e.g. routers) or a network server. It is used for correct communication between different devices. It takes the form of four numbers separated by dots, e.g. 194.75.3.2. It is also worth adding that the IP address can be either fixed (does not change, even when the device is reset) or dynamic. A dynamic IP is assigned to the computer each time it connects to the Internet.
