Has IoT-Hub endpoint fixed IP address

Petr Maslak 61 Reputation points

our customer has allowed us to configure only one fixed ip-address in firewall.
Host name for IoT-Hub in our connection string is: <CustomName>.azure-devices.net. Is it fixed IP address?
If not, have you any suggestions to solve this problem? Thank you

    Hello @Petr Maslak ,

    at this moment, the IoT hub public address is not represented as a fixed IP Address.

    Microsoft is offering lists of IP addresses used by the different Azure services and regions, called service tags.

    These lists are also slowly changing. Microsoft notifies its clients in advance.

    These lists can be downloaded or even disclosed using an API so you can theoretically automate updating the firewalls.
