Hello, I write this ticket to suggest adding Unbound as self-hosted DNS service.
I successfully use it with PiHole/AdGuard Home and thanks to that https://ipleak.net site does not report ANY DNS server my network is using.
No need to use Cloudflare, AdGuard, Quad9 or G 
gle DNS.
As a bonus redirecting all unencrypted port 53 communcation to the device Unbound is running on my router greatly increases privacy as no provider is receiving DNS queries.
Here’s a tutorial I based my setup on: Linux: Get rid of TRACKING and UNWANTED ADS with UNBOUND and ADGUARD HOME, and regain your PRIVACY! - YouTube
Cheers.
