DNS (domain name system)
DNS, a global distributed database that matches Web site URLs to a numerical IP address. DNS, which governs routing of all traffic on the Internet, contains billions of records, answers billions of queries and accepts millions of updates from millions of users on an average day.
DNS is a hierarchy of servers, including 13 master "root" servers. On the lower end of the hierarchy, every organization that has a domain name depends on the reliability of its own DNS name servers to maintain an Internet presence.
