> ISPs just haven't been enabling it. It’s a chicken and egg problem. It would have been nice if everybody everywhere agreed to build and use an entirely new network at the same time, but that was never going to be practical. The actual problem at hand was lack of address space, and I think this could have been addressed with a more viable upgrade path - turn every IP4 address into x number of addresses behind it, and allow retail ISPs to remain IP4 only.
