So DNS Black-holing is not new obviously, and what stands out as the go to solution? Pihole probably... and yeah thats what im using because hey its a popular choice. Though I am running it in docker. Combining that with Unbound (also in docker), and configuring outbound DNS to use DNS over TLS, with a few additional minor tweaks, but otherwise mostly standard configuration on both.

Wondering what you guys might be using, and if you are using Pihole and/or Unbound if you have any tips on configuration.

Happy to share my config if there is interest.
