Methods and apparatus for enabling a node that does not support Mobile IP to roam from a first Foreign Agent to a second Foreign Agent are disclosed. In a Foreign Agent that supports Mobile IP, a method of registering a node that does not support Mobile IP with a Home Agent that supports Mobile IP includes detecting a node in a vicinity of the Foreign Agent, composing a registration request specifying a node ID associated with the node, and sending the registration request to the Home Agent. When the Home Agent receives the registration request from a first Foreign Agent, the Home Agent updates a mobility binding table to associate the first Foreign Agent with the node. In addition, the Home Agent notifies a second Foreign Agent to update its visitor table to reflect roaming of the node from the second Foreign Agent to the first Foreign Agent.

1. A server configured to store and provide authentication keys upon request, the server comprising:a memory; and a processor coupled to the memory, wherein the memory and the processor are adapted to provide a plurality of authentication keys, the plurality of authentication keys being associated with a plurality of nodes, wherein the server is adapted for providing one of the plurality of authentication keys associated with one of the plurality of nodes to a Foreign Agent that supports Mobile IP in response to a request received from the Foreign Agent, the request identifying a node that does not support Mobile IP, thereby enabling the Foreign Agent to generate an authentication extension.
