Setup: Ubuntu 16.04 LTS

Introduction

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 16.04 LTS to use Quad9.

Step 1

From the Ubuntu desktop, select the Network icon (up-and-down arrows or WiFi icon) at top right corner of the screen, and click Edit Connections...

Step 2

Select the connection that you wish to modify and click Edit

Step 3a (IPv4)

Select the IPv4 Settings tab, set the Method to Automatic (DHCP) addresses only, 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 skipping Step 3b, simply click Save to complete the setup process, and then confirm you're using Quad9.

Step 3b (IPv6)

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 Settings tab, set the Method to Automatic, addresses only, enter the Quad9 IP addresses of your preferred service.

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