For that matter, if we can kill IPv4, we have plenty of headroom for a LOT of IPv6 PI space. Owen

Not sure if this is the common thought, but if anyone has a network which requires static IP assignments, they can probably justify a request for a /48 from an RIR. After all, ARIN's requirement for an end-user IPv6 block is, at minimum: "Justify why IPv6 addresses from an ISP or other LIR are unsuitable". I would think that ISP portability would satisfy this requirement, but If I'm wrong, I'm absolutely open to being corrected on this. But most home users have no need for static IPs, so the dynamic ISP assignment is perfectly fine.
I think the tech will advance fast enough that keeping up with an IPv6 route table will be a non-issue. IPv6 adoption is, unfortunately, slow enough that there will be no issues keeping up, even assuming a "slow" hardware refresh cycle.

Wait. What's the objection to ULA? Is it just that NAT is bad, or is there something new?
No particular objection, but I don’t see the point.
What can you do with ULA that GUA isn’t suitable for?
Owen
ULA provide stable internal addresses which survive changing ISP for the average home user. Now, I know you can do the same thing by going to a RIR and getting a prefix but the RIR’s aren’t setup to supply prefixes like that to 10 billion of us.
They are also in a specific range which makes setting filtering rules easier for everyone else.
Now I would love it if we could support 100 billion routes in the DFZ but we aren’t anywhere near being able to do that which would be a requirement for abandoning ULA. Until them they have there place.
