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.

    Hello @Stephens, Mike,

    welcome to this moderated Azure community forum.

    You want to know the public IP addresses of Azure Services, especially for IoT Hubs.

    Yes, Microsoft provides a list of IP ranges used by their resources, it's called Service Tags.

    You can either download the list or use the API.

    See this blog post for details.
