DNS (Domain Name System)

The DNS maps domain names into IP addresses. DNS information is distributed hierarchically throughout the Internet among computers called DNS servers.

If the DNS server cannot find the IP address, it communicates with higher-level DNS servers to determine the IP address. See also domain name.
