> The only "problem" here that is caused by IPv6 is the SD-WAN / multi-provider scenario. Even that is solvable. There are so many IPv6 addresses that your local router can have a unique routable range that it can hand out to the local network, "masking" the external internet provider addresses in the same way that IPv4 routing does it. That's not NAT, that's just routing. E.g. I have a customer that uses a non-RFC1918 public range internally and they have 5 ISP uplinks. They don't need to renumber their internal range just to fail over to another link.
Neither does anyone using IPv4.
Does your customer use BGP for that public IPv6 range? Do they have cellular links? Can they load balance some traffic over two/three links? Can they direct certain protocols over different carriers?
