DNS - Domain Name System
DNS technology allows hosts on TCP/IP networks (such as Internet Web sites) to be addressed by names. DNS includes a network protocol and a distributed data store for lookup of host names and addresses.
DNS Definition
DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites.
