How do we determine list of possible IP addresses to whitelist for IoT hub.
Is there a master list of IP addresses that a device may communicate with the IoT hub. When we ping the hostname of our IoT hub, we receive back an address of 20.44.8.225. This IP address however is not found in the Azure IP address JSON file.
