What is DNS
DNS (Domain Name System), translates domain names into IP addresses.
Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses.
Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 22.214.171.124.

Web servers are ultimately accessed by an I.P. address. When you send a request for a web page that contains a domain name that name has been translated into the I.P. address of the server along the way. There are Domain Name Servers all across the internet that accomplish this task. You set up DNS entries on one server and those setting will propagate across all the other servers around the world. You need to set up at least two different DNS records. One is a "C Name" record (common name). This is to match up your domain (i.e. example.com) with the I.P. address of the server the website files resides on. You also need to set up an "A Name" record (alias name). You set this to point another version of your domain name to what you set up as your C Name. Specifically you need to point your domain name with a "www." to the one without (so that people will get your site no mater how they type your domain name in the address bar). In other words, you use the A Name record to point Example Domain to example.com and then the C Name record points domain.com to the I.P. address of the server .You can check the DNS records related details at Whoisxy.com
