Abstract
This document defines a Mobile IPv4 Registration Revocation mechanism
whereby a mobility agent involved in providing Mobile IP services to
a mobile node can notify the other mobility agent providing Mobile IP
services to the same mobile node of the termination of this
registration. The mechanism is also usable by a home agent to notify
a co-located mobile node of the termination of its binding as well.
Moreover, the mechanism provides for this notification to be
acknowledged. A signaling mechanism already defined by the Mobile
IPv4 protocol is leveraged as a way to inform a mobile node of the
revocation of its binding.

Mobile IP [1] defines registration of a mobile node's location to
provide connectivity between the mobile node and its home domain,
facilitating communication between mobile nodes and any correspondent
