Fatal Flaw

The fatal flaw in the whole ipv4 to ipv6 transition is that BOTH networks need to be up and running for it to work. So in other words, until the world is 100% ipv6 capable, then ipv4 (and all it’s associated problems) is still required. You can’t just jump to ipv6 and leave the ipv4 behind. I really don’t know what they were thinking when they touted it as a solution to the address space problem. It may be a better protocol but a solution it is not.
