Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.
More about this video -
Domain Name Service aka DNS is the unsung hero of networking. Without DNS it would be impossible for us to traverse through this vast jungle of the world wide web.
So let's learn what is dns in a fun way? I am sure anyone even without an I.T. background would be able to understand DNS after watching this tutorial.
We will cover dns with a layman example and then take a more detailed look into how exactly dns server works. How different domains are structured into parent-child relationships. What kind of dns queries are used to reach a device over the network.
WE HAVE ADDED USEFUL TOPICS IN OUR NETWORKING AND INFRA SERIES (LINK ABOVE).
PLEASE WATCH ALL THE VIDEOS FOR BETTER UNDERSTANDING !!

[@osamakiliw]

there are 3 types of queries ( recursive, iterative and non-recursive) non when dens server will find the ip in it's cache
difference between recursive and iterative queries is the level of involvement of the DNS server in the resolution process. In a recursive query, the DNS server performs the entire resolution process on behalf of the resolver, whereas in an iterative query, the server provides the best answer it has and may refer the resolver to other DNS servers to get more information.
