What Is A DNS Server?

Before sharing the actual list of best DNS servers it’s important to know what actually is a DNS server and how can it enhance your browsing experience.

As mentioned above, DNS servers translate the human-readable domain names that you enter into a browser (like techworm.net) into the public IP address that’s needed for your device to actually open and interact with that site.

Infact, it’s impossible to access the Internet and various services associated with it without DNS servers. Consequently, ISP’s assign DNS servers to help users access the Internet. That said, the DNS servers assigned by ISP are not always the best and users generally deviate towards alternate DNS servers.

The two primary benefits of using alternate DNS servers are speed and privacy.
