As a noob who is only moderately tech savvy, how can I get started with selfhosting? Is it worth just buying a Pi to mess around with at first?

Neat, I will have to check that out! I’m guessing you can’t enable it on locked down work devices, however.

Ditto, NextDNS has been great for that. I tried their paid version as well but downgraded since I never ran into that many queries. I’ve heard good things about quad9 too, which I think is European.

You have your Pihole setup at work?
