When a device with Dynamically Assigned IP (DAIP) is created (either Interoperable Device, or Check Point object), it is "allocated" with a demo IP address 0.0.0.X.
If more than one device with Dynamically Assigned IP (DAIP) is created, the same demo IP address might be allocated to more than one of these DAIP devices.
In such case, after policy installation completes, the following warning appears:
...have same main IP address: 0.0.0.X . This can cause abnormal behavior to your network. Please change the IP address of one of these objects."
