In late March, we migrated from nginx to knot-resolver. Because of some problems with nginx, user’s switching network from LTE to wifi and vice versa cannot keep connection to dns server over tls.
With knot-resolver, we use Adguard’s DoT as backend, we plan to use other to backup soon.
We donot use dnscrypt as brigde anymore. We use knot-resolver’s DoT as client to connect backend.
Because we cannot run DoH on same port with nginx, we change DoH’s port to 4443. New address should be https://dns.infosec.xyz:4443/dns-query and boostrap address is 18.104.22.168/2400:6180:0:d1::873:7001
