IP version 6 (IPv6) is being designed within the IETF as a replacement for the current version of the IP pro-tocol used in the Internet (IPv4). We have designed protocol enhancements for IPv6, known as Mobile IPv6, that allow transparent routing of IPv6 packets to mo-bile nodes, taking advantage of the opportunities made possible by the design of a new version of IP. In Mo-bile IPv6, each mobile node is always identied by its home address, regardless of its current point of attach-ment to the Internet. While away from its home IP subnet, a mobile node is also associated with a care-of address, which indicates the mobile node's current location. Mobile IPv6 enables any IPv6 node to learn and cache the care-of address associated with a m...
