DNS is a system by means of which domain names on the Internet are translated into IP (Internet protocol) addresses. Its purpose is to facilitate the users in remembering and entering the names. It is much easier to write down and remember, for example, "www.superhosting.bg" instead of "220.127.116.11".
After a user registers a particular name, for example, "my-name.com", it is written down into a special DNS Registry. The name must be associated with the IP address of the server where the website corresponding to that name is hosted. Thus, when a user types a name into their browser, the site associated with that name is loaded.
