Encrypted DNS IoT user cases/considerations:

Main categories of IoT:

· Basic M2M / IoT devices with limited functionality so likely to only be able to support Do53. · Latest IoT devices particularly smart home devices which could support DoT and DoH going forward.

IoT sub use cases:

IoT device operate in a great many environments, each with unqiue and diverse architectures for network and DNS services

Smart Home

Smart Cities

Smart Buildings

Smart Assets

Smart Vehicles

Industrial / Enterprise

Healthcare

Questions for IoT devices capable of encrypted DNS:

Choice of DoT vs DoH on device

Whether home hubs / CPE should support local DoT / DoH proxy/stub

Core network support for DoT/DoH IoT resolvers – whether separate DNS resolvers will be required for certain categories of IoT devices (e.g. healthcare) for added resilience and security.

How to handle GDPR / informed consent aspects if no easy user interface.
