Windows 10

Overview

The easiest way to set Quad9 on your entire network is via your router settings. If you'd prefer to set Quad9 on an individual Windows device, please follow the steps below to configure Windows 10 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

  • Right click on the Network icon (Wired or WiFi) in the system tray and click Open Network & Internet Settings.

  • Click Change adapter options

  • Select Properties.

  • Select Internet Protocol Version 4 (TCP/IPv4). Then, click Properties.
