What Is A Domain Name Server (DNS) And How Does It Work?

DNS stand for Domain Name System/Service. It’s used to resolve FQDN (Fully qualified domain name) to IP address and Vice versa such as www.example.com to and vice versa.

– Domain Name systems makes it easy for the user to remember the name and access the web pages easily.

– DNS is an alternate way to provide easy to remember IP addresses and use them to access the web-services easily.

DNS is like a phone book for the internet. If you know a person’s name but don’t know their telephone number, you can simply look it up in a phone book. DNS provides this same service to the internet.
