Why would anyone switch off IPv4? That makes no sense and isn’t commonly done. You run dual stack in most cases – NAT v4 and straight v6. A lot of folks are using v6 on mobile phones without even realizing it because telcos ran the numbers years ago and realized it was cheaper to push v6 at the end user layer than run NAT and/or try to find v4 addresses on the transfer market. There’s been no unallocated pool of v4 space for almost a decade.

Yes that’s the odd part. Most people are using v6 daily without even realizing it.
