# DNS over HTTPS in Windows 11
Requires Windows 11.
- `GPO-EnforceDoH.reg` enables the group policy to require DoH. However it
didn't seem to work for me or it allowed me to set the DNS server to not
use DoH.
- `DohWellKnownServers` adds DoH support for multiple IPv4 & IPv6 addresses
that Windows 11 isn't shipping by default, currently:
- Adguard
- Cloudflare antimalware
- DNS0 (& Zero)
- Mullvad
- Mullvad Adblock
- Quad9 ECS (Windows 11 defaults include Quad9 default)
## Configuration
Once Windows knows about the DoH servers (DohWellKnownServers.reg), DNS-over
HTTPS can be enabled for:
- All networks: `Windows-I (Settings) -> Network & Internet -> Advanced network settings -> WLAN -> View additional properties -> DNS Server assignment -> Edit`
- Same place for Ethernet etc.
- Specific network: `Windows-I (Settings) -> Network & Internet -> WiFi -> Connected SSID -> DNS server assignment -> Edit`
- Note: if the all networks one is configured, there is a warning about it not being used.
