About DNS

Domain Name System (DNS) servers map the user-friendly domain names that users type into their Web
browsers (e.g., “www.yahoo.com”) to the equivalent numerical IP addresses that are used for Internet routing.

When a PC user types a domain name into a browser, the PC must first send a request to a DNS server to
obtain the equivalent IP address. The DNS server will attempt to look up the domain name in its own database,
and will communicate with higher-level DNS servers when the name cannot be found locally. When the
address is found, it is sent back to the requesting PC and is referenced in IP packets for the remainder of the
communication.
