Valve argued in court that you do not own any title in your library and that they are a subscription based service. That’s not very ethical.

Kubuntu? Whore.

Yep, that’s the one. You just set your upstream default to something like tcp-tls:1.1.1.1:853 for DoT (which is what I use anyway).

Good documentation on other features like adblocking,caching,etc: https://0xerr0r.github.io/blocky/v0.21/configuration/

Just throwing out a couple of other solutions I didn’t see mentioned for DoH/DoT:

1. CoreDNS
2. Blocky

Both of those support encryption and allow for DNSBL. If you are wanting to hand out DNS entries over DHCP it may a problem with your ISPs router there. Either replace it, sit one you do control between it and your network, or run DHCP snooping from a switch to restrict it’s DHCP.
