    No, you can block ads with a pihole. This is because Roku hard codes its dns server as 8.8.8.8. Pihole doesn’t handle IP addresses, only DNS.

      Interesting. I set an adblocking dns via DHCP and, as far as I know, the Roku respects it. Ads are blocked and I can see it failing to delivery telemetry in my dns logs (most persistent thing on the network).

      I set a rule to catch outside dns to see if anything, the roku included, has been misbehaving.

        Well, I’m back and can confirm the sneaky DNS resolver. I have two roku devices and they both were making requests to 8.8.8.8.

        Thanks for this post! TIL.
