Re: [Doh] [EXTERNAL] Re: [DNSOP] New I-D: draft-reid-doh-operator

Third party DNS/DoH providers could probably block resolution of phishing names or  botnet C&C names using the same methods as enterprises do today, but the enterprise network will not be informed that one of its devices just tried to contact a botnet C&C. It would be very nice if the IETF standardized a way to do that.

I don’t see why they wouldn’t, and I could easily envision them being obliged to do so in the future.

They say to you IP a.b.c.d which sadly is the external IP on the NAT exiting the corporate network has a problem. So great one of potentially 1000’s of devices is infected but not really much better information than that. In effect exactly what most security operations teams assume is true every day of the week.
