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.

Class Notes DNS is the Server Service that Maps Hostnames/ Domain Names to IP Addresses DNS and DHCP are different services that are generally hosted on the same server, but can be hosted on separate servers Dynamic DNS allows DHCP to automatically add Name and IP Address mapping to DNS tables. Most techs will work with DNS built into Small Business/ Home Routers or ISP Modems. Other variations of DNS are provided by Windows Servers or BIND which is used on Unix and Linux servers. A DNS implementation may ...

O DNS, do inglês Domain Name System (Sistema de Nomes de Domínios), funciona como um sistema de tradução de endereços IP para nomes de domínios.

When your computer needs to resolve a hostname (such as www.yahoo.com) into an IP address, the domain name system goes through a series of steps to deliver the answer. This video shows you what goes on behind the scenes.
This course goes through DNS or Domain Name System. This video provides an introduction to DNS, however the videos in this course are dynamic in nature. As DNS changes, videos are added or removed as required to make sure that you always have the most up to date information.

Although it can be used to do the reverse, it is primarily given a name and asked what the IP Address is for that name. This is the same principle that is used for a phone book. Given a name, a person is able to look up the phone number for that person using the phone book. Hosts File Bef...
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
