What is DNS (Domain Name System)?
The DNS (Domain Name System) is the system for converting domain names into IP addresses.
An IP (Internet Protocol) address is a set of numbers and full stops used to identify a computer using the internet. The numbers are between 0 and 255, for example, 192.158.1.38.
Every website is identified by its IP address. However, it would be difficult for us to remember the IP addresses of even our favorite websites. So, domain names were invented.
However, machines do not understand domain names. So, the domain name system is necessary to convert the domain name we understand into the IP addresses machines understand.
