I wouldn't bother buying a raspberry pi 5 to run this shit though, as the article suggests. It's way overkill. Just run the docker on another server you're running anyway, or run it on a raspberry pi zero 2W for $15. A pihole does so little work, it doesn't benefit from a pi 5. I just run it on a VPS that costs me 3€ per month and runs lots of other stuff too like an IRC bouncer. That way I can access it from everywh…
Why don't people run their own public DNS and sell you very cheap access to it? $9 a year to Johnny's No-Ad DNS. If it worked I'd pay for it
And how do you block access to non paying customers? DNS isn't autenticated.
It's also not really a great method for adblocking anymore (which would make the support problem worse, "why am I still seeing ads?")
