Best Free DNS Servers

When it comes to DNS servers, most people only understand the working and benefits of it. Less understood, however, is the difference between various sets of servers available in the market.

Domain Name Systems are an essential part of communication via the internet. Upgrading to a better DNS server will increase your website's loading speed and provide added security.

This article discusses some of the best free alternative DNS servers and explains what DNS is and why you may want to choose a better DNS provider for your website.

What is DNS?

The Domain Name System servers are the internet's version of a directory. When you want to look for a number, you must search it against a person's name. DNS works on the same concept.

Whenever you enter a website's name, it explores the server for the IP address and opens the webpage for you. It is how your computer knows how to find google.com, upwork.com, or founderjar.com.

It is convenient for us to remember domain names, like zoollery.com, instead of the IP address – 172. 67. 194. 123. However, computers don't work that way. It is much easier and faster for the computer to connect to an IP address.

Your DNS server is responsible for finding the correct IP address for the browser. The browser would then move ahead to connect to the given server and access the website for you.

What to Consider When Switching Your DNS?

The Domain Name System is a significant part of your internet business. A small error in your server can sometimes give a bad experience to your visitors.

When switching from your old DNS server, you should prioritize your preferences and look for DNS providers that provide a fast and secure server.
