How to Create a Website - Create-Website.org
A Domain Name Server is a server computer on the World Wide Web that allows us to locate other computers on the World Wide Web using a virtual domain name (e.g. mysite.com).
The role of DNS servers is to map easy-to-remember domain names to the physical location of another computer where the website is hosted.
The nodes (i.e. computers) on the Internet are identified by an Internet Protocol address (IP Address) such as "220.127.116.11".
