True, it will use the closest server that supports TLS. Unfortunately TLS is the least stable DNS protocol with the highest lookup failure rate. I have had too many complaints in the house when using DoT on our network. The closest NextDNS server to us is not enabled with DoT. So we still get routed pretty far away. DNS is highly variable based on where the user is and what is available near them. We are in a medium sized city in the US, and the closest DNS servers by hundreds of miles are our ISP servers.If you use tls/quic protocol with nextdns it will not be using anycast and its always the closest dns server gets used.
