So welcome back, guys.
Now, next, we will going to discuss the DNS mechanism in detail.
That is, we will try to understand that, how actually the DNS system works.
The goal of DNS mechanism is to find the answer to DNS query.
That is, we need to find the IP address of the host server which hosts the requested website.
So this is the entire goal of the DNS system.
That is for a given website.
We need to find the IP address of the host machine on which that particular website is hosted.
Now there are three different mechanisms to resolve the DNS query.
The first one is the recursive method.
That is DNS query is called the DNS query.
The second method is the iterative method.
The DNS query is called the iterative DNS query, and the third method is the reverse lookup DNS query.
So we will discuss each of these method of resolving a DNS query one by one.
