I configured my Asus router with asuswrt-merlin firmware to route all DNS traffics to my Adguard instance to catch those apps and devices with hard-coded DNS. Those routed DNS queries appear in adguard as originating from my router’s IP address, so I can easily see what apps and devices trying to bypass my dns. Turns out the main offender is Netflix.
My router doesn’t log the target dns server ip address, but according to many forum threads, netflix apps seems to hardcode the dns to 8.8.8.8 and 8.8.4.4.

That’s interesting. What IP address is netflix hardcoding?
