Domain Name Server

On the Internet, the Domain Name System (DNS) associates various sorts of information with domain names; most importantly, it serves as the "phone book" for the Internet by translating human website addresses (eg www.google.com) to computer hostnames, (e.g. 66.230.200.100, the IP address) that networking equipment needs for delivering information. It also stores other information such as the list of mail exchange servers that accept email for a given domain. In providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.

Without a domain name server and the information it provides, computers wouldn't know where to find your website or any other website
