EzIP proposes to deploy 240/4

So each RAN has no possibility of redundant connections? Nobody

of scale would accept such a limitation. It also looks like an

opportunity for telcos/governments to partition their part

of the internet and impose whatever censorship they wish.

As such, the collection of RANs forms an overlay network 

layer wrapping around the current Internet core. Consequently, only the 

SPRs in the RAN need to be able to transport 240/4 addressed packets.

You previously described this as like connecting CG-NATs together via a

VPN. I don't see why we'd want to add maintaining a global VPN to

already difficult peering relationships. It could be used to exlude non

EzIP club members.

This is why we talk about enabling new (but based on existing design) 

routers to use 240/4 netblock for serving as SPRs, but not perturbing 

any routers in the current Internet.

As it's a CG-NAT variant why are you delaying yourself by requiring

new address space that will take a long time to become available? Why

not use the already allocated space for CG-NAT? Sure it's only a /10

but that's an already (probably too) large RAN.

It also seems unfeasibly optimistic that if the work was done globally

to make 240/4 useable that they'd want to dedicate it to the as yet

undeployed EzIP. You might stand more chance if you gained some

critical mass using the existing available 100.64/10 & rfc1918 space,

and then those that find they need more in one RAN will make the case

for 240/4 when it becomes necessary for them. Is 240/4 special to

EzIP such that alternative numbers may not be used?

I would like to share one intriguing graphics (see URL below) that 

is almost perfect for depicting the EzIP deployment configuration. 

Consider the blue sphere as the earth or the current Internet core and 

the golden colored land as the RANs. By connecting each continent, 

country or all the way down to a Region to the earth via one IPv4 

address, we have the EzIP configuration. With this architecture, each 

RAN looks like a private network.

That sounds an entirely undesirable goal for the internet.

Too many today don't remember the towers of Babel world prior to the Internet. If they did they'd understand that building on this type of idea is like burying yourself.... And any customers so unwise to get involved
