The Domain Name System (DNS) is a distributed database used by computer systems to map between hostnames and IP addresses, and to provide electronic mail routing information. Each site (university department, campus,company, or department within a company, for example) maintains its own database of information and runs a server program that other systems across the Internet can query. The DNS provides the protocol which allows clients and servers to communicate with each other.
