I think there is some confusion in this thread between "resolver" and "DNS server". Your base installation always has a resolver, typically part of your libc. This one is the piece responsible for looking up host names (and typically configured via /etc/resolv.conf); it may do some caching. The DNS servers are the things queried by the resolver (among others, like /etc/hosts). A caching resolver overlaps in function somewhat with a local DNS server, perhaps thus the confusion. And then there are browsers doing DoH. Pure evil, if you ask me. Cheers -- t
