The following may sound like out-of-the-blue. To expedite the discussion, however, allow me to state that it has been in reviews at the highest levels of responsible organizations without receiving a shot yet. So, please enjoy the information. The IPv4 address shortage issues have been resolved. We came upon a scheme that can expand each public IPv4 address by 256M (Million) fold without affecting the current Internet. A proposal called EzIP (phonetic for Easy IPv4) has been submitted to IETF: https://tools.ietf.org/html/draft-chen-ati-adaptive-ipv4-address-space-03 https://tools.ietf.org/html/draft-chen-ati-adaptive-ipv4-add... Essentially, among other benefits, EzIP can establish a sub-Internet capable of serving an area with up to 256M IoTs from just one IPv4 address. This is bigger than the largest city (Tokyo metro) and 75% of the countries. This can realize the CIR (Country-based Internet Registry) model proposed by ITU a few years ago stealthily even without setting up a CIR organization. If a government is not interested in this resources, private enterprises can make use of it to provide "local" Internet service in parallel to the current "global" Internet services, very much like the Independent telephone companies in the PSTN industry. The current Internet then becomes the backbone / infrastructure / skeleton for interconnecting these sub-Internets, yet only for carrying inter sub-Internet traffic, very similar as the electric grid supporting islands of renewable energy generated by individual homes and businesses. Consequently, there will be a lot of spare IPv4 addresses for quite sometime to come. Then, much of the efforts in deploying IPv6 are no longer needed. Thoughts and comments will be much appreciated.
