Abstract
Embodiments disclosed herein provide systems, methods, and computer readable media for extending the lifetime of a network address when an address system is unavailable. In a particular embodiment, a method provides, upon determining that a first network address for a network element has reached a preferred lifetime for the first network address, transitioning the network element to an extended rebind state that allows the first network address to remain in the preferred state. While the network element is in the extended rebind state, the method provides attempting to contact an address system and determining whether a second network element is assigned the first network address. The method further provides maintaining the first network address in the preferred state and the network element in the extended rebind state until contact is made with the address system or the second network element is determined to be assigned the first network address.
