DNS explained
The Domain Name System, or DNS for short, is the Internet’s system for mapping alphabetic names to numeric Internet Protocol (IP) addresses. It is like a phone book that maps a person’s name to a phone number. Every time when a Web address (URL) is typed into a browser, a DNS query is made to learn an IP address of a Web server associated with that name.
