DNS over TLS (DoT) is supported and uses port 853 by default. DoT is required for Android's "Private DNS mode" (available since Android 9.0 Pie).

To use Client ID identifiers, you must add a wildcard subdomain alias of the form *.adguard.domain.com.
DANIAN sets up a wildcard alias in advance.

The phone can be configured in the Private DNS settings as below:

Select Private DNS Mode

- Off

- Automatic

- (SELECTED) Private DNS provider hostname: myphone.adguard.domain.com

Then click SAVE
