Exactly, many previous unsuccessful discussions at IETF about 240/4: IPv6 is the only viable long-term solution.
The effort to “reinvent” any part of IPv4 or patches to it, then test that everything keeps working as expected, versus the benefits and gained time, it is much best invested in continue the IPv6 deployment which is already going on in this region and the rest of the world. It would not make sense, to throw away all the efforts that have been already done with IPv6 and we should avoid confusing people. I just think that even this thread is a waste of time (and will not further participate on it), time that can be employed in continue deploying IPv6.

Reasonings against it were that the released space will be consumed quickly (at that time, NAT already existed but was uncommon) and that new IP will be designed and deployed quickly (we were optimistic). Masataka Ohta There have been many discussions about 240/4 in the IETF. For some examples, query “240/4” in the ‘ietf’ mail archive on mailarchive.ietf.org. —gregbo ********************************************** IPv4 is over Are you ready for the new Internet ? http://www.theipv6company.com The IPv6 Company This electronic message contains information which may be privileged or confidential.
