What is DNS?
Domain Name System (DNS) is a protocol under which a domain address is converted into an 
IP address and redirects the browser to a particular web server where the website files are 
hosted. This server then returns the requested web page and displays it in your device’s 
browser. A domain name system can also be termed a Directory of the Internet, where it 
searches for the IP address associated with the specific domain name. Each device connected 
to the internet has a unique IP address, using which other machines communicate with it.

stored the requested information.
The whole process starts when you try to access a webpage from your 
browser, it tries to search for all the resources that require DNS lookup and it 
has to wait for some time (average waiting time is 20-120 milliseconds) until 
the complete lookup process end and before it begins to download anything.
