OpenWrt LuCi


The OpenWrt Project is a Linux operating system targeting embedded devices, which is often used as an open-source solution for routers and firewalls.

This guide covers setting Quad9 in the DNS forwarder settings. When using your OpenWrt router as a DNS server, it will forward DNS requests to Quad9.

Backup Time!

Before making changes to a production environment, we recommend backing up the existing configuration


  • Log into your LuCI control panel, typically by opening in your browser.

  • Navigate to Network -> DHCP and DNS

    • Set and, or the addresses of your preferred Quad9 service in the "DNS forwardings" input fields.
  • If your network supports IPv6, you can also add 2620:fe::fe and 2620:fe::9, or the IPv6 addresses of your preferred Quad9 service.

  • Navigate to Resolv and Hosts Files sub-tab, and make sure Ignore resolv file is Enabled.

  • Click Save & Apply at the bottom. Since you are not changing the DHCP settings, the change should be instantaneous .

Verify Configuration

  • Confirm you're using Quad9 on Linux, MacOS, or Windows.
