The truth is that very very few people run their own recursive nameserver. The entirely reasonable assumption for any authoritative nameserver, like .com, is that the query is being asked on behalf of someone else and knowing that a user of your nameserver asked for the ip of sexysheep.com doesn't give them a lot of useful info.
I'm think many ISPs actually sell a lot of data from their recursive nameservers, but I'm willing to bet that almost no-one bothers to sniff port 53 udp traffic going elsewhere.
My vote for the best privacy option is always going to be just run pi-hole with your own recursive nameservers.
But then the internet can know that you are the one using your own nameservers and so they can trivially identify your traffic.
Really you need to use some public resolver with a critical mass of other users in order to have any hope for anonymity. But then of course you have to trust that resolver too.
``` cargo install numa
# set mode = "odoh" in numa.toml ```
