perform a network action based on the received notification; and

store a result of the received notification in a database, comprising to:

update an identifier of a plurality of identifiers, the plurality of identifiers relating to various devices, the identifier corresponding to the device;

group the plurality of identifiers into a first group and a second group; and

synthesize a root identifier linking the first and second groups together; and

perform, by the IF-MAP server, a network action based on the received notification, the network action relating to a search for information in the first group and the second group based on the synthesized root identifier so that the search is performed without prior knowledge of any specific identifier in the first or second groups; and

a memory coupled to the processor and configured to provide the processor with instructions.

10. The system recited claim 9 , wherein the notification includes DHCP lease updates from the DHCP server, and wherein the processor is further configured to:

11. The system recited claim 9 , wherein the notification includes DHCP lease update publications from the DHCP server, and wherein the processor is further configured to:

publish by the DHCP server an DHCP lease update;

receive by the IF-MAP server the DHCP lease update;

generate by the IF-MAP server a second notification to an IF-MAP client;

communicate by the IF-MAP client the DHCP lease update to a discovery engine; and

conduct by a discovery engine network device discovery and assessment based on the DHCP lease update.

12. The system recited claim 9 , wherein the processor is further configured to:

store the notification received from the DHCP server in the IF-MAP server.

13. The system recited claim 9 , wherein the notification includes DHCP lease publications from the DHCP server.

14. The system recited claim 9 , wherein the notification includes DHCP lease add, drop, and modify publications from the DHCP server.

15. The system recited claim 9 , wherein the notification includes DHCP lease updates from the DHCP server.

16. The system recited claim 9 , wherein the notification includes DHCP lease update publications from the DHCP server, and wherein the processor is further configured to:

publish by the DHCP server an DHCP lease update;

receive by the IF-MAP server the DHCP lease update;

generate by the IF-MAP server a second notification to an IF-MAP client;

communicate by the IF-MAP client the DHCP lease update to a discovery engine;

conduct by a discovery engine network device discovery and assessment based on the DHCP lease update; and

store by the IF-MAP client results of the network device discovery and assessment based on the DHCP lease update in the database.

17. A computer program product for performing network action based on dynamic DHCP updates, the computer program product being embodied in a non-transitory, tangible computer readable storage medium and comprising computer instructions for:

subscribing by an IF-MAP server to receive a notification from a DHCP server, the notification includes a network address and a unique device identifier combination of a device;
