Abstract
This document specifies protocol enhancements that allow transparent
routing of IP datagrams to mobile nodes in the 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 its current point of
attachment to the Internet. The protocol provides for registering
the care-of address with a home agent. The home agent sends
datagrams destined for the mobile node through a tunnel to the care-
of address. After arriving at the end of the tunnel, each datagram
is then delivered to the mobile node.
