This chapter provides an overview of the functionality provided by the HP-UX Mobile
IPv4 product. Mobile IPv4 provides transparent routing of IP packets to a mobile IP
device, such as a portable computer, regardless of the mobile node’s point of attachment
to the network. Mobile IPv4 allows a mobile node to move from one wireless access point
or base station with no disruption in network connectivity.
