The Domain Name System (DNS) ensures the availability of websites, email and Web systems by mapping domain names to Internet protocol (IP) addresses, for example, 188.8.131.52(IPv4) or 2001:503:A83:0:0:2:30(IPv6).
The DNS uses specialized servers to translate names such as www.Verisign.com
into IP Addresses that allow data and information to reach its destination. This process, called DNS resolution
, allows people to type more memorable domain names into a browser to reach websites and send email messages.
