Who do you use for upstream DNS?

There are so many good options for upstream DNS other than your internet provider I figured I would ask everyone, please post a comment below. Here are some of my favorites but its by no means an inclusive list. Wikipedia has a longer list here Public Recursive Name Server . My current favorite is 1.1.1.1 followed by Google and OpenDNS and Quad9 I don’t actually use but its not a bad choice for home users.

There is 1.1.1.1 by Cloudflare
