Ditto. But as I recently found out, running two of these helps prevent outages and can be really helpful since many devices inject their own DNS at the tail end of the list, sometimes capped at two. So if you run two with one as redundant, you get two benefits:
1. If one ever fails, it just fails over to the backup seamlessly
2. It also helps prevent DNS injection by things like Amazon, etc. though I suspect this is going to be fixed as updates and new versions roll out.
The biggest threat is DNS over HTTPS. Billed as “encrypted for your safety” when really it’s 100% a way to prevent you from using DNS level blocking. Unless you want to block all HTTPS traffic from your router which, ungood. I fucking hate DoH.
