Free trial then $20USD per year for ControlD. Is that what you use? If so, why do you use this over another service?

Not OP but I also use ControlD. I admittedly like NextDNS interface better, but honestly, I rarely need to login anyways.

So why ControlD? Because I don't want to run my own piHole, basically. They maintain ad block lists that you can edit as you see fit to add things or relax things that may cause issues(which you can't do easily with public ad blocking dns servers).

Why ControlD then and not NextDNS? First, because their support was awesome when I had an issue. AFAICT it was the founder actually emailing me back and forth, and it ended up being my ISP's fault, but I only knew that based on research provided to me by support. Secondly, I got a good deal on a 5-year subscription at one point.

Happy to answer any questions, not affiliated but a fan of the service.

Not GP, but I just run my own dns inside the network (unbound on a little openbsd sbc) with a cronjob that pipes oisd.nl into it every night, works great..
