Computers with Internet access communicate with one another via the Internet Protocol (IP) and always have an IP address (IP number), e.g. 158.64.1.25, assigned by the ISP (Internet Service Provider). The Domain Name System (DNS) was developed because remembering these IP addresses (numbers) is difficult. The DNS enables users to enter words or names instead of numbers. In other words, a domain name is an Internet address.
