The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for the purpose of locating and identifying computer services and devices with the underlying network protocols. By providing a worldwide, distributed directory service, the Domain Name System is an essential component of the functionality of the Internet.
The Domain Name System deligates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over sub-domains of their allocated name space to other name servers. This mechanism provides distributed and fault tolerant service and was designed to avoid a single large central database.

What is DNS
DNS Resolution, Step by Step
It's a cold world, sometimes I feel all alone
It's a long road, that I'm rolling on
And I wonder, if I'm on the path I should have taken
And I'm still here, even though my heart is breakin'
Chorus: Someday I'm gonna find what I'm looking for
Someday I'll find my place in this world
Someday I'm gonna know why I'm here
When I find, what I'm looking for
It's a big old world, and sometimes I lose my way
But I keep searching, and I get closer every day
I can't look back, and I can't go back in time
I gotta move one, and leave the past behind
