5 Best Third-Party Free and Public DNS Servers You Can Use

In this blog post, I am going to talk about free Public DNS servers that you can use on your computer while using the internet. Also, I will be explaining that how you can change the DNS on your Windows computer and Router as well. Before we talk about those 5 best free and Public DNS servers, I would like to talk about DNS.

What is DNS?

DNS stands for Domain Name System. DNS Server has the information which offers client computers to resolve memorable, alphanumeric names to IP addresses which is what computers use to communicate on the network with each other. In other words, DNS is quite similar to a phone contact book that keeps the information about all the domain names on the internet and translates them to IP address. This is important because Domain names are easy to remember for humans but computers access sites using their IP addresses which are mapped to their respective domain names. That is why we see domain name with TLD in the browser while opening any website. But, if you know the IP of that particular website (if it has a dedicated IP), then you can access the site by typing its IP address as well. DNS just translates domain names to IP address to make computers work easier as they identify IP addresses.

When you take an internet connection, you get an IP address, and DNS is also maintained by your ISP. Moreover, you can use publicly available free DNS servers as well for various reasons.

Why Should You Use a Public DNS server?

I have listed 5 best free public DNS that you can use whenever you need. But, why should you use a public DNS server?

Here are the 4 reasons you should use a public DNS server:

  1. Access Blocked Content

If your ISP has blocked some websites on their network, and you are using their default DNS, then you won’t be able to access those websites. Since they do blocking using DNS mostly, you can switch to a public DNS for free and unblock those blocked websites and contents.

You can also access Geo-blocked content as that blocking is also done using DNS settings in most cases, and when you use third-party DNS, you might be able to access those Geo Blocked content as well.

  1. Speed Improvements

If your ISP is not providing good internet speed, you can try any public DNS and then test because in many cases, switching to third-party public DNS; speed improves to a good extent. However, there is no guarantee of speed improvement.

  1. Parental Control

As you read earlier in this blog post that many public DNS like Open DNS gives you the option to block certain websites or group of websites on your network. This is helpful if you have kids in the home, and you don’t want them to access adult content or any harmful websites. Moreover, this is not a great security measure because if your kids are smart, they can change the DNS and access the content because it is quite easy to update the DNS on your computer.

  1. Security

Free Public DNS servers like Google Public DNS and Open DNS offers the security measures that your ISP might not have implemented yet. Also, such third party DNS servers are good at filtering the phishing websites, malware sites, etc. Moreover, not all third-party DNS do content filtering, for example; Google DNS doesn’t do it because it mainly aimed at making your internet faster.

How to Change DNS on Your Windows PC?

On Windows, it is quite easy to change the DNS servers. Currently, I am using Windows 10. So, this guide is for updating the DNS server on Windows 10.

  • Go to Control Panel. You can do it by just typing “Control” in the Run, and hit enter.
  • Click on Network and Internet.
    change DNS on PC
  • Click on Network and Sharing Center

  • Click on Change Adapter Setting.

  • You will see there Network connections.

  • If you are using via Ethernet cable, that will be active, but if you are using via Wifi, then that will be active. Now right click on the network that is in use, and click Properties.

  • Now, Double click “Internet Protocol Version 4 (TCP/IPv4)

  • Make sure you ticked “use the following DNS server addresses”, and enter the DNS server you want to use. For example, I have entered Google Public DNS.

Click Ok to save the settings. Now, your DNS is switched to Google Public DNS. This way you can enter any other third-party DNS server.

How to Setup Third-Party DNS server on Your Router?

This can be a bit tricky because not all of us use the same router so settings might be different. I am currently using Denboomband’s internet, and when I open router setting, I see the name “Skyworth”. If you are using the same, you can just log in to your router setting. Go to Network >> WLAN.

And, select Set DNS Manually, and enter the DNS servers. And Click Apply Changes.

Moreover, if you are using a different router, you can go to settings, and try finding the DNS setting, and update that to switch to third-party DNS server.

Conclusion

Third party free public DNS servers are useful in many cases as you read in the article. So, why not use them because we don’t need to pay anything, and we get better control of our network connection.
