One of the most annoying things that you can ever encounter is slow internet and buffering. We are living in a cyber world where the internet is the backbone so without it, we feel like traveling back to the stone age.

What is DNS?

DNS stands for Domain Name System and it is very similar to a phonebook.

In simple terms, DNS is a translator. It converts any domain name such as google.com  to a machine-understandable (i.e computer-readable) numerical IP (Internet Protocol) address like 06.04.1405.6; which allows the web browser or an e-mail client to load data from the web. DNS is important for a computer or any such equivalent devices to load a particular website using IP addresses.

In this module, we’ll be discussing some of the best DNS Servers available in the market.
