11. The system of claim 1 , wherein the storage is included in a database managed by an Internet Protocol Address Management appliance.

12. The system of claim 1 , wherein the storage includes a data record for each virtual machine in the virtual cloud.

13. The system of claim 1 , wherein the virtual resource is removed from the virtual cloud and updating the storage includes removing from the storage, information associated with the virtual resource.

14. The system of claim 1 , wherein the processor is further configured to organize the collected information in a hierarchical format to be displayed.

15. A method of processing infrastructure metadata information, comprising:

collecting one or more infrastructure metadata information about a virtual resource of a virtual cloud, wherein

collecting the infrastructure metadata information includes collecting at a device external to the virtual cloud, information about the virtual resource,

the virtual cloud includes a virtual switch,

the infrastructure metadata information includes information about a plurality of virtualization tiers, and the virtual resource is associated with least one of the plurality of virtualization tiers,

collecting information about the virtual resource includes collecting from a hypervisor, information about a first tier of the plurality of virtualization tiers pertaining to a physical layer of the virtual resource,

collecting information about the virtual resource includes collecting from an infrastructure manager that manages the hypervisor information about a second tier of the plurality of virtualization tiers, the collected information about the second tier includes an identifier of the virtual switch that has been automatically discovered, and

collecting information about the virtual resource includes collecting at the device external to the virtual cloud from a cloud manager that manages the infrastructure manager information about a third tier of the plurality of virtualization tiers; and

using the collected information to manage IP address provisioning of resources of the virtual cloud that includes the virtual resource, wherein managing the IP address provisioning of the resources of the virtual cloud includes using the collected information to automatically determine an available IP address for a new virtual resource to be added to the virtual cloud and using the determined IP address to automatically register the new virtual resource with a Domain Name Server.

16. The method of claim 15 , wherein collecting the information includes receiving the collected information at an Internet Protocol Address Management appliance.

17. The method of claim 15 , wherein the collected infrastructure metadata information includes information that identifies a location of the virtual resource in the virtual cloud.

18. The method of claim 15 , wherein the collected infrastructure metadata information includes one or more of the following: a fully qualified domain name, an Internet Protocol address, a Media Access Control address, an operating system metadata, a virtual data center metadata, an infrastructure manager metadata, a hypervisor metadata, a virtual entity metadata, a virtual cluster metadata, a virtual host metadata, a host server metadata, a virtual switch metadata, a virtual entity type metadata, an extensible attribute, a virtual resource container metadata, an organization metadata, a cloud metadata, a data center metadata, and an external network metadata.
