I would not be surprised if our standard #IPv4 peters out over the next decade or two. There are already multiple layers of work arounds (such as NAT and CGNAT) that make certain things more difficult than they should be.
I wouldn't be surprised if an "IPv4B" comes out (basically the same thing, but all existing addresses are prepended with "2.2.2.2", leaving a much larger address space for future expansion. This IPv4B would likely run alongside IPv6 ... but would require software upgrades across almost every network attached device and hardware upgrades to routers and switches globally.

Back in my networking classes in the 1990s, they told us that odd numbered versions of the IP protocol are experimental, while even numbered versions are deployed / deployable. #IPv4 vs #IPv6

I had a new experience a few days ago. For the first time, I had an #IPv6 only connection. No #IPv4 at all, and the laptop isn't set up for 4-in-6 tunnelling. If I had thought about it, I would have launched my VPN, to see how well it handles that situation.
That's a signal that any software that connects to networks needs to be capable of handling such connections now. It isn't just a "one day this will happen" anymore.

@moonman I wonder if there are still any free #IPv6 in #IPv4 tunnels out there. I'm pretty sure SIXXS is shut down.
Such a tunnel might be a way to get IPv6 back for your instance.

Yes. I had rented a cheap #VPS which only had an #IPv6 address. I wound up swapping it with one of my sons, who had a VPS with only an #IPv4 address.
