What Is a Domain Name System (DNS)?

A Domain Name System (DNS) is like a phone book for the Internet. It keeps track of domain names (the part of a web address that comes after “www.”) and the long string of numbers (called an “IP address”) associated with that website.

Without DNS services, you’d need to type something like 172.16.254.1 every time you want to go to a particular website. Instead, you can just type the easier-to-remember website name.

Essential Elements of DNS

Domain Name Registration

Every domain name must be registered with a domain name registrar — a company that keeps track of who owns which domains.

Web Servers

Web servers store your website’s information, such as the text, images and video that make up your website.

Website Hosting

Website hosting companies provide you with online access to the web servers you need, saving you the money and hassle of purchasing and managing servers yourself.

Name Servers

Name servers are the servers that run DNS software. Your website’s DNS information is stored on those name servers, which are hosted and managed by your DNS hosting company.
