This request is for custom domain and custom SSL certificate support for the IoT Hub endpoint. This work is currently unplanned for IoT Hub but we’re listing to customer requests and may chose to support this in the future.
If you have interest in have a deterministic way of understanding your IoT Hub IP address (and corresponding geo-pair IP address) in order to keep firewall rules up-to-date, see and vote on this request: https://feedback.azure.com/forums/321918-azure-iot/suggestions/15714243-iot-hub-network-address instead.Denis Oliana commented
This would be a great feature - also in regard to being more flexible. Imagine the scenario where an IoT-Hub gets deleted (by accident, or on purpose because of some reconfiguration) and it has to be made sure, that the same DNS can be regained for the devices to be able to communicate. BTW: the same goes for the DPS.Denis Oliana supported this idea ·
