A notation used to represent the unique IP addresses of computers on a TCP-IP network. It consists of four integers separated by three dots. Each integer is less than or equal to 255. For example, 22.214.171.124 is an example of an IP address expressed in this notation. It is sometimes referred to as dotted decimal notation. This notation is only rarely used since symbolic domain names allow meaningful names to be used for computers on a network. The Internet Domain Name Service converts from domain names to dotted quad form.
