Ah yes… the IPv6 migration. Been hearing about this for two decades now. The reason it isn’t ubiquitous in 2021 is because there are fundamental issues with the protocol, not least of which is incompatibility with what the entire rest of the world is current running. If we are ever going to get the world on the same protocol, we need something new.

Nah, as protocol the IPv6 is fine.

What is not fine is the real-world implementations. ISPs that give you a /64 subnet? ISPs that insist, that with IPv6 you must use their CPE as a router, where you have almost zero control? ISPs that give you /56, but prefix delegation on the router they force on you is broken?

There's so much brokenness, that even as a IPv6 fan, I keep my IPv4 addresses. And if it means DS-Lite or IPv4, then IPv4 is it.

Do you mind describing what those issues are? Or linking some reading about it?
