The Domain Name System (DNS) is the method by which internet domain names are located and translated into Internet Protocol addresses.

The domain name provides an easy to remember way to reach these addresses. Instead of typing in a string of numbers, the domain name can be used to navigate to sites. When a user types in a domain name, another server looks up the domain name and appropriate IP number, and then sends the user to the correct site. DNS load balancers assist in traffic management for networks.
