What is DNS ?

It associates various information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often used analogy to explain the Domain Name System is that it serves as the 'phone book' for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com translates to DNS is down, it doesn't matter if your servers, storage, and network are up – your Web site is not available. And yet for many IT and business professionals, DNS is a mystery.
