0) Re: Ur. Pt. 2): This topic is such a tongue-twister. Let's put it
aside for now, until I can properly convey the EzIP concept and scheme
00) Re: Ur. Pt. 4): Okay, I was concerned about how to decipher
this cryptic exchange. So let's put it aside as well.
1) Re: Ur. Pt. 1): Yes, you are correct that the EzIP network
architecture looks like that of CG-NAT. In fact, it is exactly the same.
This is actually the beauty of the EzIP solution. That is, without
touching the hardware, by implementing the EzIP technique (*/disabling/*
the program code that has been */disabling/* the use of the 240/4
netblock), an existing CG-NAT module becomes a RAN! As to universal
peer-to-peer, where is any of such today? On the other hand, upon fully
implemented the EzIP proposal (the second phase: making use of the
Option Word in RFC791), an IoT in one RAN can directly reach a second
IoT in another RAN world-wide. So that the original promise of the
Internet will be finally fulfilled and for the long haul.
2) Re: Ur. Pt. 3): Similarly, you probably only recognized the part
that EzIP proposes to classify the 240/4 netblock as the fourth private
address in RFC1918, but overlooked that such capacity will enable a RAN
to cover a geographic area as big as Tokyo Metro, or 75% of smaller
countries around the world, even before utilizing the conventional three
private netblocks. This puts 240/4 into a different league from the
other three conventional private netblocks, although all four have
basically the same technical characteristics. Now, visualizing each RAN
is tethered from the existing Internet core by one umbilical cord (one
IPv4 address), it appears like a private network. So that each RAN can
provide Internet services by utilizing existing technologies, while
avoiding those undesired. Combining these RANs around the world, an
*/overlay/* layer of routers (SPRs) can operate in parallel to the
current Internet. Under such a configuration, the latter no long is
involved with daily local activities, but only carries inter-RAN
traffic, very much like the division between national and international
telephone networks. This creates quite a different operation landscape.
Please have a look at slide # 11 of the below whitepaper for a rough
breakdown of the available addresses under the EzIP scheme. Furthermore,
if used diligently, (treating IP address as "*/natural resources/*"
instead of "*/personal properties/*"), the assignable "EzIP addresses"
can last quite awhile.
3) Re: Ur. Pts. 5) & 6): I believe that there is a philosophic /
logic baseline that we need to sort out, first. That is, we must keep in
mind that the Internet community strongly promotes "*/personal
freedom/*". Assuming that by stopping others from working on IPv4 will
shift their energy to IPv6 is totally contradicting such a principle. A
project attracts contributors by its own merits, not by relying on
artificial barriers to the competitions. Based on my best understanding,
IPv6 failed right after the decision of "not emphasizing the backward
compatibility with IPv4". It broke one of the golden rules in the system
engineering discipline. After nearly three decades, still evading such
fact, but defusing IPv6 issues by various tactics is the real impedance
to progress, not only to IPv4 but also to IPv6.
