I just discovered this and it works fantastically on any old / unused android device you might have lying around, I was shocked at how easy it was, all the instructions are there, once you have it running all you need to do is set your router DNS settings to your pihole IP address and presto! Ads and trackers are gone!
Running a pi-hole doesn’t require much juice. It’s a fancy DNS server, not a router. First gen raspberry pis were pretty weak and even those things didn’t even break a sweat.
Another person who doesn’t know what they are talking about
For home use, they barely do much. At an enterprise level, then it’s another story.
You try browsing with 50ms average pin to a dns server where a website loads thousands of objects :(
