Is there anything in this field that actually doesn't block DNS but hijacks it and serves up 1x1 GIF for any image requests, 1 frame videos, empty HTML, CSS, JS, fake VAST/VPAID files so that requests don't have to timeout and fail? I setup a pi-hole a couple of years ago and the kids begged me to shut it off because it screwed up with games on their phones (crashed if they couldn't load ads or got stuck because there was no reply).
I think you can configure PiHole to return whatever IP you want for blocklisted domains. I guess you could set up a box with nginx that inspects the request content type header and returns generic content. But, TLS will cause problems here. You’d need to MITM all the traffic and serve up your own root certs, install them on devices etc.
Yeah TLS will be the headache. Just did a quick test with a self-signed, that works fine but I'll need to create one for each TLD (wildcard doesn't seem to be allowed as root, at least in browsers). That's easy to script, hard to install. So the only issue are devices that I can't install certs on like our Apple TV's and Rokus.
PiHole & AdGuard are DNS blockers. Those tools are only serving/blocking domain mame requests. So they are not aware of the actual request your client is sending to those servers (to for example download a file). So no, by the nature of the DNS protocol this is not possible with those tools. What you probably wanna do is to use some kind of proxy which does deep package inspection (be aware that this is very resource intensive since you have to break up encryption and stuff).
Properly not worth it for the task you described. Simply add a DNS whitelist to AdGuard or manually unblock those domains causing issues.
If people can figure out which names resolve to ads and block them, people can figure out which names resolve to tracking pixels and send it to a server that will hand back a pixel.
Or you could buy your kids some decent games rather than training them to suffer through ads or pay-to-win in-app purchases? This is the best feature of Apple Arcade in my opinion.
We'll I decided to teach them they have to pay for stuff themselves, and at least it taught them to be rather frugal. The real problem is that they mostly play what the other kids are playing.
