An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned to devices participating in a computer network. A network may contain multiple computers or others devices each having their own IP address (or addresses).
Internet sites such as whatismyipaddress.com can automatically detect my IP address when accessed through the Web browser. These sites only work if that computer is connected to the Internet. Additionally, on a home network these sites may not find that computer's address but the address of a network router instead.
