I set it up a long time ago, so I don’t honestly remember. I followed some guide, and did a few domain redirects to point at stuff on my home network and to shut Zuck out of my life, but I didn’t do anything crazy. So, I doubt it, but I don’t know.

I have a mini PC that is always on that runs my NTP and DNS, and it’s upstream DNS is quad nine out of Switzerland. (9.9.9.9). I tend toward the same usage patterns daily, and about a third of my requests never leave my home DNS to get resolved.
