the difference between thinking in terms of 128 bits vs 2^128 addresses which seem to be conflated in these discussions I think you're wrong. Show me where anyone made a case in this thread at all for 2^128 addresses mitigating the problem. Everyone has been discussing structured assignments with 128 bits, and several people here have proven to a mathematical certainty that no technology here today nor on the horizon can exhaust this address space undertake the current allocation rules, *INCLUDING* using /64s for point-to-point circuit. -mel On Dec 28, 2017, at 11:34 AM, "bzs@theworld.com<mailto:bzs@theworld.com>" <bzs@theworld.com<mailto:bzs@theworld.com>> wrote: On December 28, 2017 at 19:23 mel@beckman.org<mailto:mel@beckman.org> (Mel Beckman) wrote: IPng was discussed to death and found not workable. The history is there for you to read. In the meantime, it's not helpful claiming IPng until you understand that background. By "IPng" I only meant whatever would follow IPv4, IP next generation, not any specific proposal which may've called itself "ipng". But more importantly the difference between thinking in terms of 128 bits vs 2^128 addresses which seem to be conflated in these discussions, repeatedly. -- -Barry Shein Software Tool & Die | bzs@TheWorld.com<mailto:bzs@theworld.com> | http://www.TheWorld.com<http://www.theworld.com> Purveyors to the Trade | Voice: +1 617-STD-WRLD | 800-THE-WRLD The World: Since 1989 | A Public Information Utility | *oo*
