Top 16 best free and public DNS servers in 2024

Top 16 best free and public DNS servers in 2019

Domain Name Servers (DNS) are the internet’s equivalent of a phone book, holding all the domain names found online and turning them into IP addresses. While we may not see that there is a need for this as we can remember domain names, computers run differently and need IP addresses in order to function. With that in mind, this article will outline the very best providers of DNS servers out there.

DNS servers use specific software in order to reach each other and pass on the information. Though DNS servers do make things a lot easier for us when surfing online, it is important to remember that they are still vulnerable and can suffer from a range of attacks. This means that it is very important that you have an anti-malware protection system in place.

Both the primary and secondary servers will be configured to your router, which can be helpful because if one fails, the other can pick up the slack. Throughout the rest of this article, we will discuss the features of various DNS server providers, showing you which ones are the best and why.

For those familiar with changing their DNS, here’s a reference table with primary and secondary server addresses.

  • Primary DNS:
  • Secondary DNS:

Of course, Google was going to be the number one pick on the list of free DNS servers. Google Public DNS was started in 2009 and has enabled millions of internet goers to enjoy a great online experience.

Google Public DNS offers complete support for IPv6 connections, allowing you to meet any requirements needed to set up this type of connection. It offers great security and is great for those users who aren’t always able to access the internet with fast internet speeds. The bonus is that its free for everyone.

  • Secondary DNS:

OpenDNS is another one of the most popular public DNS servers. This one is geared towards power users. Not for the uninitiated, this DNS server provides a great server replacement for those who are looking to have complete control over their settings. There are two options, Personal and Business, both of which have dedicated parental controls, excellent speed, and great phishing protection.

The Personal version is free, but for the extra features, there is a payment plan in place if you are keen to try out those extra controls. Really, the only downside here is that it can be a bit confusing for users that aren’t power users.


  • Primary DNS:
  • Secondary DNS:

CloudFlare is considered one of the fastest DNS services, if not the fastest, out there. Though it is one of the newest DNS services available, it has quickly made its mark thanks to its great speed.

It also is great in the protection department as it can block malicious domains.

To round off these features, it is also completely free making it one of the best DNS servers on the current market. If there was a downside, we’d have to say that the security protection can be a little bit too much at times.


  • Primary DNS:
  • Secondary DNS:

DNS.Watch is another server that is among the top fast DNS servers out there. While not as fast as some (we’re thinking Google and CloudFlare here), DNS.Watch still provides great up time and good speeds. It operates under DNS neutrality so there is no change in the performance when you’re using it and it doesn’t allow any intrusions.

It’s also completely free, which is always a bonus. To use it, your IP addresses need to be changed to and As if all this wasn’t enough, it can be used on almost all devices including Windows, Mac and Linux systems. The one weakness this server has is a lack of top security features.

    DNS.Watch is and NOT !

    I spent so much time diagnosing my DNS problems because of this typo

  2. Thomas G May 27, 2019 at 12:39 pm

    I’ve heard of Cloudflare as being one of the best out there ! I still have a hard time understanding everything concerning IT, or exactly visualizing all those concepts, but your articles are really helpful.

  3. Joe April 24, 2019 at 12:27 pm

    Very useful information, thank you. Getting a good DNS server is very important, and people should take it more seriously. Google Public DNS works well enough for me.

  4. Tim J February 24, 2019 at 10:26 am

    I’ve heard a lot of good things about CloudFlare, it sounds like the best to me. I don’t know much about the others but The Google public DNS sounds really interesting as well.

  5. S. D. February 2, 2019 at 10:04 am

    The Google Public DNS is pretty cool especially since it’s free but if you truly want the top of the line try CloudFlare. Great uptime and top speeds. Haven’t tried the others on this list and I don’t know if I will ever need to or want to.

  6. Sticky Note3 January 27, 2019 at 2:16 pm

    I’m currently using Quad9 and I’m quite satisfied, but sometimes it blocks websites that are perfectly safe. That’s a little annoying, so I’ll be looking for another alternative. Thanks for the list.
