Fedora 38

Overview

The easiest way to set Quad9 on your entire network is via your router settings. If you'd prefer to set Quad9 on a single system, please follow the steps below to configure Fedora 38 to use Quad9.

Firefox, VPNs

  • Firefox is set to use Cloudflare DNS by default in some regions. If you're using Firefox, check that this is disabled.
  • VPNs typically do not respect the system or router-level DNS settings. If you're using a VPN, configure Quad9's IP addresses in the Custom DNS settings of your VPN client. Refer to your VPN provider's documentation for further information.
