- Abbreviation of Domain Name System, or Domain Name service. Over the Internet, a system which translates a domain name, such as www.yipeeee.com, into an IP address, such as 18.104.22.168. The DNS maintains a database which correlates domain names with the appropriate IP addresses. A domain name may have more than one IP address associated with it, and an IP address may also have more than one domain name associated with it. Although an IP address or a domain name may be entered in the address field of a browser, the latter is more often used as it is generally easier to remember.
