....as the size of the internetwork grows. The Internet, in particular, currently consists of over 6 million individual hosts, and this number has been doubling approximately every year. Indeed, new levels of hierarchy have been added to the Internet addressing scheme with subnetting [21] and CIDR [9], and additional support for further hierarchy is planned in IPv6, the new version of IP currently being designed for the Internet [2] It is this hierarchy, however, that defeats host mobility. With hierarchal addressing and routing, packets sent to a mobile host can only be routed to the mobile ....

....addressing and routing has proven to be essential to keep up with the exponential growth of the Internet, in particular. The original two level hierarchy of Internet addressing in IP has already been transparently extended at the bottom with subnetting [16] and at the top through use of CIDR [5]. In the IETF s IPng effort to develop the next generation of the IP protocol [2] support for many more levels of hierarchy than in the present version of IP is an explicit design goal [15] However, this hierarchy in addressing and routing prevents packets from being routed correctly to a ....
