10 Best Public DNS Servers in 2021: Comparison & Review

This guide will discuss 10 best free public DNS servers, including Google, OpenDNS, Quad9, Cloudflare, CleanBrowsing, Comodo, Verisign, Alternate, and Level3.

In the digital world of today, we cannot think about spending our lives without the internet. DNS or Domain Name System is a familiar term on the internet. In general, it is a system that matches domain names such as Google.com or Facebook.com to the correct IP addresses. Still, do not get what it does? Let us look at it this way. When you enter a domain name in a browser, the DNS service translates those names to specific IP addresses that will allow you to access these sites. Get how important it is now?

Now, as soon as you connect to the internet, your ISP is going to assign you random DNS servers. However, these are not always the best options to go with. The reason behind this is that DNS servers that are slow are going to cause a lag prior to when websites begin to load. In addition to that, you might not get access to the sites as well.

That is where free public DNS services come in. When you switch to a public DNS server, it can make your experience so much better. You are going to face a lot less technical issues thanks to the lengthy 100% uptime records as well as more responsive browsing. Not only that, these servers block access to infected or phishing sites, making your experience much safer. In addition to that, some of them even come with content filtering features that help keep your children away from the dark sides of the internet.
