NAT doesn't solve everything, and creates a whole new class of problems that you can just avoid by adopting IPv6 natively. And it's definitely not being ignored at larger companies.
In particular, just off the top of my head...
- T-Mobile US doesn't even assign clients an IPv4 address anymore. Their entire network is IPv6 native.
- Many cloud providers charge extra for IPv4 addresses, but give IPv6 addresses out for free.
For trivial cases NAT is easy, for complex situations it's a nightmare. I've been fighting a lonely battle against multiple-NAT VPNs as being the solution to the wrong problem for longer than I care to remember, and I'm tired boss. A few years ago we had a client site go offline because a local network guy just didn't like IPv6 and turned it off, not realizing that a huge amount of stuff was happening automatically and that's why he hadn't been needing to work on it.
