STEPS TO REPRODUCE

- hosts: localhost
  connection: local

  gather_facts: false

  tasks:
    - name: Create a network interface
      azure_rm_networkinterface:
        subscription_id: my-subscription-id
        resource_group: my-resource-group
        name: testnic001
        virtual_network: /subscriptions/my-subscription-id/resourceGroups/some-resource-group/providers/Microsoft.Network/virtualNetworks/vnet-name
        subnet_name: subnetname
        create_with_security_group: false
        ip_configurations:
          - name: ipconfig1
            private_ip_allocation_method: Static
            private_ip_address: 172.16.0.5

    - name: Change network interface private ip
      azure_rm_networkinterface:
        subscription_id: my-subscription-id
        resource_group: my-resource-group
        name: testnic001
        virtual_network: /subscriptions/my-subscription-id/resourceGroups/some-resource-group/providers/Microsoft.Network/virtualNetworks/vnet-name
        subnet_name: subnetname
        create_with_security_group: false
        ip_configurations:
          - name: ipconfig1
            private_ip_allocation_method: Static
            private_ip_address: 172.16.0.6

EXPECTED RESULTS

The interface gets provisioned with static IP 172.16.0.5 in the first task, then it gets updated to 172.16.0.6 in the second task. Re-running the playbook should change it back to 5 and 6 again.

PLAY [localhost] ****************************************************************************************************

TASK [Create a network interface] ***********************************************************************************
changed: [localhost]

TASK [Change network interface private ip] **************************************************************************
changed: [localhost]

PLAY RECAP **********************************************************************************************************
localhost                  : ok=2    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

ACTUAL RESULTS

After the interface is initially created, the IP will not be updated. This can be done via Azure portal without any issues. Running the playbook a second time will report zero changes.

PLAY [localhost] ****************************************************************************************************

TASK [Create a network interface] ***********************************************************************************
changed: [localhost]

TASK [Change network interface private ip] **************************************************************************
ok: [localhost]

PLAY RECAP **********************************************************************************************************
localhost                  : ok=2    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

Additional information

In the code, the logic is described to be supposed to compare the dicts of existing config with desired config, explicitly mentioning private_ip_address:

The problem appears to be that construct_ip_configuration_set does not include private_ip_address:
