The domain name system (DNS) is a naming database in which internet domain names are located and translated into Internet Protocol (IP) addresses. The domain name system maps the name people use to locate a website to the IP address that the computer uses to locate that website.
For example, if someone types, xyz.com into a web browser, a server behind the scenes maps that name to the corresponding IP address. An IP address is similar in structure to 203.0.112.67.
Web browsing and most of the other internal activities rely on the DNS to quickly provide the information necessary to connect users to remote hosts. DNS mapping is distributed throughout the internet in a hierarchy of authority. Access providers and enterprises as well as governments, universities and other organizations typically have their own assigned ranges of IP addresses and an assigned domain name.
In DNS system, the DNS server converts the URLs and domain names into IP addresses that computers can understand and use. They translated what a user types into a browser into something the machine can use to find a webpage. This process of transition and lookup is called DNS resolution.
