Ubuntu 20.04 and 22.04

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 Ubuntu 22.04 or 22.04 LTS 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.

Instructions

IPv4

  • From the Ubuntu desktop, select the drop down menu in the top right corner of the screen, expand either Wired Connection or Wireless Connection based on your connection type, then select Wired Settings or Wireless Settings.

  • Click the ⚙ icon next to your connection.

  • Click the IPv4 tab

    • Disable Automatic DNS
      • Enter the Quad9 IP addresses of your preferred service.

Multiple IP addresses can be entered in the list using comas.

9.9.9.9, 149.112.112.112

  • If you will not use IPv6, click Apply to complete the setup process, and then confirm you're using Quad9.

IPv6 (Optional)

If your network/computer support IPv6, it's also recommended to configure the Quad9 IPv6 addresses. If you're not sure if IPv6 is configured on your network, you can test that here: https://test-ipv6.com/

  • Select the IPv6 tab
    • Disable Automatic DNS
      • Enter the Quad9 IP addresses of your preferred service.

Multiple IP addresses can be entered in the list using comas.
