I don't agree with this take. I think it's actually quite a bit more complex, and this is a large part of the reason adoption has been slow. In retrospect, I think it would have been better off in practice to just literally extend the size of IPv4 addresses, and make it as simple as converting all IPv4 systems to hold a larger address.
- James_K 2y agoI feel like the hard part there is actually accessing all the IPv4 systems to change how they handle addresses. I don't know the full scope of difference, but I feel like once you can do a software update to all of your devices, the cost of increased complexity in protocol would be relatively constant between a minimal and actual v6. You are just pushing different data through the update.
