An IPv4 home address may be shared by many mobile terminals distinguished by port numbers, which is why IPv6 is not necessary.
An IPv4 address can also be shared by many mobile terminals distinguished by AOL userids. How did that work out?
The point is that all the transport layer protocol have port numbers. So, if you have a stable IP address and, say, 256 stable port numbers, your mobile device running applications as a server, can be reached by the port number, distinguished from other mobile devices sharing the IP address. Such a service might cost $10 a month or Gree might offer it free of charge. Masataka Ohta
