Which DNS Server Do I Use?


Scott Campbell

When it comes to browsing the internet, you may not realize it, but there’s a crucial component that helps you access websites seamlessly – the DNS server. But how do you know which DNS server to use? In this article, we’ll explore different options and help you make an informed decision.

What is a DNS Server?

DNS stands for Domain Name System. It’s like a phone book for the internet.

When you type a website address in your browser, the DNS server translates that human-readable domain name into a computer-readable IP address. This allows your browser to connect to the correct web server and load the website content.

Using Your ISP’s Default DNS Server

By default, your Internet Service Provider (ISP) assigns you a DNS server. While this option is convenient, it may not always be the best choice. ISPs often prioritize their own network traffic over other DNS requests, resulting in slower browsing speeds.

If you’re facing slow website loading times or frequent timeouts, it may be worth considering alternative DNS servers.

Public DNS Servers

Public DNS servers are operated by organizations separate from your ISP. They aim to provide faster and more reliable browsing experiences.

Google Public DNS

Google Public DNS is one of the most popular options available. It offers fast response times and supports additional security features like DNSSEC (Domain Name System Security Extensions). To use Google Public DNS, set your primary DNS server to 8.8.8, and secondary server to 8.4.4.


OpenDNS provides various filtering options that allow you to block certain types of content or websites. It also offers additional security features. To use OpenDNS, set your primary DNS server to, and secondary server to 208.220.220.

How to Change Your DNS Server

To change your DNS server, follow these steps:

  1. Open the Control Panel on your computer.
  2. Select “Network and Internet” or “Network and Sharing Center”.
  3. Click on “Change adapter settings”.
  4. Right-click on your network adapter and select “Properties”.
  5. In the properties window, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
  6. Select the option to “Use the following DNS server addresses”.
  7. Enter the primary and secondary DNS server addresses provided by your chosen DNS service.
  8. Click “OK” to save the changes.

Note: The steps may vary slightly depending on your operating system.


The DNS server you use can significantly impact your browsing experience. While your ISP’s default server may be convenient, alternative public DNS servers like Google Public DNS and OpenDNS offer faster speeds and additional security features.

To change your DNS server, simply follow the provided steps for your operating system. Experiment with different options until you find one that suits your needs best.

Remember, a faster and more reliable DNS server can make all the difference in ensuring a smooth browsing experience!
