Mobile IP Administration Guide

Care-of Addresses

Mobile IP provides the following alternative modes for the acquisition of a care-of address:

Co-located care-of address enables a mobile node to function without a foreign agent, for example, in networks that have not yet deployed a foreign agent.

If a mobile node is using a co-located care-of address, the mobile node must be located on the link identified by the network prefix of this care-of address. Otherwise, datagrams destined to the care-of address are undeliverable.
