Well the DNS protocol has been defined on UDP and TCP port 53, so if you block this, you block DNS. If you add TCP/853 into the mix you block DNS over TLS, all of which is relative easy for an enterprise to do. > Malware or > non-cooperating applications can do name resolution by other means.

A malware doing something specific to it is different than an IETF standard and application providers taking this standard (DoH) to switch a basic internet function (name lookups) without the users consent which are due to using HTTPs/443 harder to block for enterprises. It is a pretty clear difference. So long -Ralf —-- Ralf Weber
