Quite simply, expecting the vast amount of legacy ipv4-only equipment out there in the world that is 10, 15, 20 years old to magically become compatible with the use of 240/4 in the global routing table is a non viable solution. It is not a financial reality for many small to medium sized ISPs in lower income countries.

The amount of time and effort that would be required to implement your proposal is much better spent on ipv6 implementation and various forms of improved cgnat.

Trying to extend the use of ipv4 space resources for a few more years is directly analogous to building sand castles on the beach when the tide is obviously coming in.

Dear Eric:

0) Your opinion by itself is very valid and much appreciate. However, it
is from a very remotely related perspective. That is, you are looking at
the financial disadvantage of the less developed regions. What I am
talking about is the generic issue of communication system address
management that applies across the board. This subject is normally
designed by system planners. The result is given to the product
development engineers who usually do not have enough knowledge to
question it.

1) The IPv4 address pool depletion issue was caused by the poor
"resources management" concepts. In this case, the insistence on the
Internet addressing should be flat (instead of hierarchical) led to the
quick depletion of the finite sized 32-bit pool. The fact is that the
current prevalent CDN (Content Delivery Network) business model based on
CG-NAT configuration is a clear hierarchical network, anyway. All what
EzIP proposes is to make it explicit and universal for improving the
performance.

2) To create a viable hierarchical network with depleted address pool
like IPv4 was practically an impossible task. Fortunately, the 240/4
netblock is available because it was "reserved for future use" ever
since 1981-09, yet no clear application cases could be found. So, this
is a natural resources that will benefit everyone without reference to
financial status, although the developing regions can benefit more by
utilizing it to leap frog out of the current disadvantaged situations.

Hope this explanation makes sense to you.
