What DNS Server Should I Use for IPv6?

When it comes to selecting the right DNS server for your IPv6 connection, there are a few factors to consider. The Domain Name System (DNS) is responsible for translating domain names into IP addresses, and having a reliable and efficient DNS server can greatly improve your internet experience.

Why Choose an IPv6 DNS Server?

IPv6 is the latest version of the Internet Protocol, designed to replace the aging IPv4 protocol. It offers several advantages, including a larger address space and improved network performance. To fully utilize the benefits of IPv6, it is important to use a DNS server that supports this protocol.

The Benefits of Using an IPv6 DNS Server

Better Performance:

An IPv6 DNS server can provide faster response times and reduce latency, resulting in improved overall performance. This is especially important when accessing websites or services that have transitioned to an IPv6 infrastructure.

Improved Security:

Using an IPv6 DNS server can enhance your online security by supporting newer security protocols such as DNSSEC (Domain Name System Security Extensions). These extensions help prevent unauthorized modification or tampering of DNS data.

Selecting an IPv6 DNS Server

Now that you understand the importance of using an IPv6-supported DNS server, let’s explore some popular options:

  • Google Public DNS: Google Public DNS supports both IPv4 and IPv6 connectivity. It offers fast response times and advanced security features like secure transaction support.
  • Cloudflare: Cloudflare provides a free, privacy-focused DNS resolver called “1.1.”

    It supports both IPv4 and IPv6 connections and boasts fast performance and robust security measures.

  • OpenDNS: OpenDNS is another popular choice for DNS resolution. It offers both IPv4 and IPv6 support, with additional features like content filtering and malware protection.

It is worth noting that the performance of DNS servers can vary depending on your location and network conditions. It is recommended to test different DNS servers to find the one that offers the best performance for your specific setup.

Configuring Your Device to Use an IPv6 DNS Server

Once you have chosen a suitable IPv6 DNS server, you need to configure your device to use it. The process may vary depending on the operating system you are using, but here are some general steps:


  1. Go to “Network and Sharing Center” in the Control Panel.
  2. Select your network connection and click on “Properties.”
  3. In the Properties window, select “Internet Protocol Version 6 (TCP/IPv6)” and click on “Properties.”
  4. Choose the option to use specific DNS server addresses and enter the IPv6 address of your chosen DNS server.
  5. Save the settings and restart your computer for the changes to take effect.


  1. Navigate to “System Preferences” from the Apple menu.
  2. Select “Network” and choose your network connection from the list on the left-hand side.
  3. Click on “Advanced” and go to the “DNS” tab.
  4. Add your preferred IPv6 DNS server address by clicking on the “+” button.
  5. Click “OK” and then “Apply” to save the changes.


Configuring DNS settings on Linux can be done through various methods, including editing network configuration files or using network management tools specific to your distribution. Consult your distribution’s documentation for detailed instructions.

By following these steps, you can ensure that your device is using an IPv6 DNS server, which will optimize your internet experience and take advantage of the benefits offered by IPv6.

In conclusion, selecting the right DNS server for your IPv6 connection is crucial for optimal performance and security. Consider the options available, test different servers, and configure your device accordingly to enjoy a fast and reliable internet experience.
