What is DNS?

 Let me make it very simple for you all.

Imagine that there’s no naming system for us. We all are identified to each other by our ‘Date of Birth’. How many people’s identification (DOB) will you be able to remember? Not much, right?

Now, let’s come to the reality. We all have a unique name to get recognized. These unique words (name) are way simpler to deal with than the combination of date, month and year (DOB), isn’t it? And this is how we communicate easily and conveniently.

This is the exact concept used in DNS (Domain Name System).

Every websites on internet are hosted in a public IP address - Wikipedia, which is a 32-bit long unique number used for the identification of each networking devices.

Similar, to the above stated example, it would be very difficult for human beings to memorize these public IP addresses while accessing the websites. So, DNS came into existence to make it convenient for us to access websites by the domain names rather than the public IP address

Thus, whenever we type an URL (domain name) in our browser, in the back end, it gets mapped into the respective public IP address and that’s how we are able to access the same website. This is all done by DNS.

Wondering how to find out the public IP address of a website?
Just open the command prompt of your PC by typing ‘cmd’ in search area. In the prompt, type ‘nslookup <website domain>’, you will be provided with name and address of the website you search for.
Or you can use various websites like Mxtoolbox (https://mxtoolbox.com/).

The Domain Name System (DNS) is the complete database of the Internet. Humans access information online through domain denominations. Any web browsers run with IP addresses. The role of DNS is to translate domain names to IP addresses.

Each contrivance connected to the Internet has a unique IP address which other machines use to find the contrivance. DNS servers eliminate the desideratum for humans to memorize IP addresses such as 192.168.1.1.

The process of DNS resolution involves converting a hostname into a computer-cordial IP address (such as 192.168.1.1). An IP address is given to each contrivance on the Internet, and that address is indispensable to find the congruous Internet contrivance - like a street address is utilized to find a particular home. When a utilizer wants to load a webpage, a translation must occur between what utilizer types into their web browser (Example Domain) and the machine-amicable address indispensable to locate the Example Domain webpage.
