This is a 20-minute broad overview of the current challenges in the DNS ecosystem for network operators and policy makers. It is intended for a technical audience. It discusses some of the issues surrounding applications doing their own DNS (e.g. DoH), end user privacy issues, the issue of increasing DNS resolver centralization, a brief update on the KSK roll, and it goes over a recent DNS attack that was very interesting called DNSpionage.
