[dns-operations] DNS over TCP query uptick with iOS 13?

[Xavier Beaudouin]

Hi !

I work for a Luxembourg company that provide Wifi in the street of luxembourg cities (and some other places too).

I saw that DNS over TLS (not TCP) eg port 853/TCP is more and more used.

I don't have any graphs about its usage but yes our dnsdist is more and more used.

(have to figure how to make nice statistics with librenms)

Regards,
