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.
I always name them, but I have no naming scheme per se, other than vibes. First car I ever owned was a light blue 83 Cutlass - that was “Bob”. Had an early 90s Dodge Shadow with a v6 and that was “Pepe.” Most recent is a 2010 VW Final Edition convertible w/ blue & white two tone paint and she’s “Elsa.” The names just always seem to be there already when I get them.
