How they are going to block servers who have DoH url? DNS level block or IP block. May be SNI level block but in few years we will have ESNI.

To access a DNS-over-HTTP server, you need its IP (otherwise it would be a circular problem - must have DNS to access DNS). So they can just block the IP/port.
