An IP mobility solution for mobile network(s) (110) defining mobile routers (112) detachably connected to one or more mobile nodes (116). When attached to the router, the nodes create a binding between their home address and a home address of their attached router. The router creates a binding between its mobile subnet prefix (or home address) and a care of address. The bindings are sent to various correspondent nodes (126) having sent packets to the nodes. The bindings are updated, as appropriate, responsive to movement of the mobile network to other networks, including other mobile networks, and/or responsive to the nodes detaching from the mobile network and roaming independently to other networks, including other mobile networks. The correspondent nodes store the bindings and updates, if any, in a binding cache (208) and consult the binding cache to determine how packets should be directed on next attempt(s) to reach the node.
