Domain names stand for Internet Protocol (IP) numbers used by computers to identify web sites and e-mail. They are found within the universal resource locator (URL). An example or a URL: http://www.yourname.com. Domain names are made up of two sections separated by a dot (sometimes called the root). The rightmost part is referred to as the top-level domain (TLD), e.g., dot com, dot net, dot org. To the left of the dot is the unique domain name, technically called a second-level domain. An example: yourname.com A specially programmed computer, called a domain name server, is used to translate domain names into Internet protocol (IP) numbers. Since people relate to words and phrases much better than numbers, the domain name system (DNS) was developed. |
