IPv4 is done; it served its purpose well, thank you. We need a date where IPv4 is no longer routed on the Interne t. I am suggesting 4/4/2024. Whatever the timeline, we need to agree on the d ate and drive toward a common goal for a better Internet.My 2 Canadian cents :-) JackJust as nobody is preventing you from going ipv6 only right now, I advocate against hindering anybody going ipv4 only for as long as they want/can.
There is nothing stopping you experimenting with class E addresses behind a NAT. Talk to your vendors to lift the restrictions and route the packets as unicast packets. Note this really doesn't help with the global shortage.
You may not like the results, but that does not make a top down approach any better a choice.
Turning Class E into global unicast is nearly as big a project as getting IPv6 deployed everywhere. There is lots of equipement that can't make the jump. Even starting 15 years ago we would still not be in a good faith position to hand the addresses out to be used by anyone to talk to anyone. Both end boxes have to support it and all the routers in between have to support it. It's not just about being able to assign the address locally. Its about everything involed in the path being able to route to/from the addresses. Keeping IPv4 going longer required more publically routeable IPv4 space and class E was never it.
