I configure my router to divert all UDP/53 to my pi hole. The advertising industry hates this type of behaviour, but it means ever an IoT device using hard coded dns (rather than what I tell them from my dhcp or nd settings) This is a feature. That some people choose terrible ISPs is a trivial problem to avoid, far easier than avoiding terrible user agents which are beholden to their advertising masters.
