Abstract

This document specifies a protocol which allows nodes to remain reachable while moving around in the IPv6 Internet. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node's current location. IPv6 packets addressed to a mobile node's home address are transparently routed to its care-of address. The protocol enables IPv6 nodes to cache the binding of a mobile node's home address with its care-of address, and to then send any packets destined for the mobile node directly to it at this care-of address. To support this operation, Mobile IPv6 defines a new IPv6 protocol and a new destination option. All IPv6 nodes, whether mobile or stationary, can communicate with mobile nodes.

Abstract

   This document specifies a protocol which allows nodes to remain

   reachable while moving around in the IPv6 Internet.  Each mobile node

   is always identified by its home address, regardless of its current

   point of attachment to the Internet.  While situated away from its

   home, a mobile node is also associated with a care-of address, which

   provides information about the mobile node's current location.  IPv6

   packets addressed to a mobile node's home address are transparently

   routed to its care-of address.  The protocol enables IPv6 nodes to

   cache the binding of a mobile node's home address with its care-of

   address, and to then send any packets destined for the mobile node

   directly to it at this care-of address.  To support this operation,

   Mobile IPv6 defines a new IPv6 protocol and a new destination option.

   All IPv6 nodes, whether mobile or stationary, can communicate with

   mobile nodes.
