Abstract
A system and method for managing logical and physical address state lifecycles. A state of unknown can be assigned to an address when the state has not been assigned. The state of the address is changed when communication is targeted to the address. The state can be changed to unfulfilled when the communication includes an address resolution protocol request sent to a device having the address when a time limit for a response to the address resolution protocol request has not expired. The state can be changed to virtual when the communication is received at the address when the state of the address is unfulfilled, and a time limit for responding to the communication expires before a response is sent. The state can be changed to unknown when the state of the address is not unknown, and the address does not participate in the communication within a time limit.
