Each computer connected to the Internet or any network has an address known as an Internet Protocol address (IP address). The IP address takes the form of four numbers separated by dots, for example: 123.45.67.890. If the computer does not have an IP address then it cannot connect to a network. A web address is also an IP address, for example this is Google’s IP address http://216.239.51.100/. This points to a server connected to the internet where Google pages are held.
