What Preferred DNS Server Should I Use?


Heather Bennett

When it comes to internet connectivity, the Domain Name System (DNS) plays a crucial role in translating human-friendly domain names into machine-readable IP addresses. Every device connected to the internet relies on DNS servers to resolve domain names and access websites. However, not all DNS servers are created equal, and choosing the right preferred DNS server can significantly impact your internet experience.

What is a Preferred DNS Server?

A Preferred DNS Server is the primary DNS server that your device uses to resolve domain names. It acts as the first point of contact when your device needs to translate a domain name into an IP address. By default, your device usually uses the DNS server provided by your Internet Service Provider (ISP) as the preferred DNS server.

Why Should I Consider Changing My Preferred DNS Server?

While using your ISP’s default DNS server might seem convenient, there are several reasons why you might want to consider switching to a different preferred DNS server:

  • Better Performance: Some alternate DNS servers are known for their faster response times, which can result in quicker website loading speeds and smoother browsing experiences.
  • Improved Security: Certain preferred DNS servers offer enhanced security features such as built-in protection against malware, phishing attempts, and other online threats.
  • Bypassing Restrictions: In some cases, certain ISPs may block access to specific websites or impose restrictions on content. By using an alternative preferred DNS server, you may be able to bypass these restrictions and access blocked content.

How Do I Choose a Preferred DNS Server?

Choosing the right preferred DNS server depends on various factors such as your location, internet service provider, and personal preferences. Here are some popular options:

Google Public DNS

Google Public DNS is a widely-used and reliable preferred DNS server option. It offers fast response times, improved security measures, and supports both IPv4 and IPv6 addresses. To use Google Public DNS, set your preferred DNS server to:

IPv4: 8.8.8 and 8.4.4

IPv6: 2001:4860:4860::8888 and 2001:4860:4860::8844

Cloudflare DNS

Cloudflare DNS is another popular choice known for its speed and security features. It also supports both IPv4 and IPv6 addresses. To use Cloudflare DNS, set your preferred DNS server to:

IPv4: 1.1.1 and 1.0.1

IPv6: 2606:4700:4700::1111 and 2606:4700:4700::1001


OpenDNS provides users with a range of options, including parental controls, malware protection, and content filtering settings. Set your preferred DNS server to:

IPv4: and 208.220.220

IPv6: 2620:119:35::35 and 2620:119:53::53

How to Change Your Preferred DNS Server?

The process of changing your preferred DNS server varies depending on the operating system you are using.

Windows: Go to the Control Panel, navigate to Network and Internet, and select Network and Sharing Center. From there, click on Change adapter settings, right-click on your network connection, select Properties, choose Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), click on Properties again, and enter the preferred DNS server addresses in the designated fields.

Mac OS: Open System Preferences, go to Network, select your network connection from the left sidebar, click on Advanced, navigate to the DNS tab, and add the preferred DNS server addresses by clicking on the ‘+’ button.

Linux: The process may vary depending on your specific Linux distribution. In general, you can modify the DNS settings by editing the /etc/resolv.conf file or using network configuration tools specific to your distribution.


Your preferred DNS server can have a significant impact on your internet experience. By choosing a fast and reliable preferred DNS server like Google Public DNS, Cloudflare DNS, or OpenDNS, you can potentially enjoy improved performance and enhanced security while browsing the web. Remember to follow the appropriate steps to change your preferred DNS server based on your operating system for seamless connectivity.
