From IPv4 vs. IPv6 To .... IPv4++



Is IPv4 exhausted?

The current model of address allocation is over, of course, but IPv4 can go on
into another simple schema which can be applied on IPv4 addressing model!



The figure shows a detailed link between two terminal points (end-users) in a transmission in three steps.
ISP1 is a unique point of access for Net1.
ISP2 is a unique point of access for Net2.
IPv41 and IPv42 must be different into the Main Network address space.
but IPv4_1(Net1) and IPv4_2(Net2) CAN BE EQUALS!



The figure shows a schema with a unique Main Network address space and
multiple independent areas each having an independent address space.
Each independent area can have another topology of network.
The transmission of data between different areas will be made only through the Main Network. Inside any independent area the transmission is between an IPv4,
as a source address, and another IPv4, as a destination address.


Some stories:
1. Two class mate: Im John. Im Dave.
2. Two Englishmen: Im Dave from London. Im Dave from Kent.

In the computer terms:
3. Inside the same area: Im IPv4_1. Im IPv4_8
4. Different areas: Im IPv4_8 from ISPi. Im IPv4_8 from ISPj.
