Sample results for this search are shown in the table below. The results show all the public IP addresses provisioned in the environment. This data could be the foundation for asset management data collection. Inventory and asset management tracking is considered a best practice in the ITIL framework. A search like this can be used to gather information on provisioned assets, in this case virtual networks. Asset management is critical in the cloud because it affects operation expenses, as well as security, and informs lifecycle management.  Public IP addresses are not free.
