Set Up: macOS - IPv6

Quad9 is a free security solution that uses DNS to protect your systems against the most common cyber threats. You can setup Quad9 on your Mac in 4 easy steps.

As the world rapidly approaches the exhaustion of all available IPv4 addresses, many are transitioning to IPv6 which has far more available addresses. Please follow the steps below to ensure you are utilizing Quad9 as your IPv6 DNS resolver.

IPv6 is configured automatically on most versions of macOS so most users can simply jump to step 1 but if you have configured your devices IPv6 settings and wish to revert back to the defaults, Apple has documentation on how to do this in their macOS User Guide: Use IPv6 on Mac

Step 1

On your Mac, choose the Apple menu > System Preferences, then select Network.

Step 2

Click Advanced and then select the DNS tab. From the DNS tab, select the "+" symbol.

Note: If you have any other DNS providers configured, you will want to first select their servers and then select the "-" symbol to remove them before adding our service.

Step 3

Enter the appropriate Quad9 IPv6 addresses for your needs. Once you have the addresses entered, select OK. We strongly suggest entering both a primary IPv6 and a secondary IPv6 address as a precaution.

For more information on which server is right for you, please visit our Quad9 IPs and Other Settings page.

Most users will want to enter 2620:fe::fe and 2620:fe::9 in the list.

Step 4

Select Apply. You are now using Quad9.
