IPv6: The NEW Generation Internet
IPv6 will not replace IPv4 since IPv6 was designed to cater for many deployment scenarios, starting with extension of the packet technology and therefore supporting IPv4 with transition models to keep IPv4 working even for ever; and then to cater for new uses and new models that require a combination of features that were not tightly designed or scalable in IPv4 like IP mobility, end-to-end connectivity, end-to-end services, ad hoc services; to the extreme scenario where IP becomes a commodity service enabling lowest cost deployment of large scale sensor networks, RFID, IP in the car, to any imaginable scenario where networking adds value to commodity. This is called sustainable growth of the Internet and progress to the new generation Internet.
