We have Azure Cloud Discovery in place to discover both Cloud Resources and Horizontal IP based discovery.
IP address information is missing for some of the Azure VMIs due to which Horizontal discovery don't get trigger for those devices. (Horizontal Discovery schedule for cloud don't require IP ranges to be defined as it automatically gets IPs from NIC "cmdb_ci_nic" table as per below KB).

What we observed is if no public IP address is discovered for cloud account in "Azure - Public IP (LP)" pattern, NIC pattern "Azure - NIC (LP)" don't get trigger resulting no private IP address getting discover for any of the VMIs in that cloud account.
Some of the cloud accounts won't have public Ip address but that shouldn't have dependency to discover NIC. Please let me now if anyone encounter similar issue where IP address/NIC info is missing for VMIs resulting no horizontal discovery for those accounts?
