It may be the devices not honouring your DNS directives. Sometimes they will still reach out to their own resolvers.
It helps if you have a network perimeter firewall to block unauthorized DNS usage.
- JackGreyhat 5y agoI think youtube serves ads from its own domain, as a first party. This makes it harder for a pihole to block. Ublock does it differently, looking at elements etc...a pihole just tries to block dns requests to ad domains, not looking at code that your browser is trying to load.
