AB We consider the problem of providing network access to hosts
whose physical location changes with time. Such hosts cannot
depend on traditional forms of network connectivity and routing
because their location, and hence the route to reach them, cannot
be deduced from their IP address. We present protocols that
seamlessly integrate mobile hosts into the current IP networking
infrastructure. They are primarily targeted at supporting a
campus environment with mobile computers, but also extend
gracefully to accomodate hosts moving between different networks.
The key feature is the dependence on ancillary machines to track
the location of the mobile hosts.  Our protocols are designed to
react quickly to changing topologies, to scale well, and not to
place an overwhelming burden on the network.
