Self-hosted

You can use Netlify CLI or workerd (Recommended) to serve locally.

Make sure you can connect to upstream servers.

If you find a bug on self-hosted, try to reproduce it at dohna.ovh before reporting it.

Apple MobileConfig API

MobileConfig can configure system-level DNS over HTTPS for Apple devices.

dohna.ovh has already enabled this API; you only need to edit a few parameters to point the URL to your domain, so there is no need to enable this API for your self-hosted instance.

Query Parameter	Default	Description
domain	dohna.ovh	Specify the DNS over HTTPS domain.
name	Dohna NS	Specify the name of the generated MobileConfig.
desc	Yet another DNS over HTTPS relay.	Specify the description of the generated MobileConfig.
