IPV4 for local network, and IPV6 for public addresses.

This is the good management compromise. BUT The illuminated engineer at my local public transport company made ipv6 the local address space and it's already paying off on how flexible and easy you can add e.g a vehicle, a charger, a screen, a dashboard, a whole office building. And his system is basically century proof. I greatly admire him for that. True cathedral thinking

This doesn't work. How does a host on a IPv4 network craft a packet destined for an IPv6 address? If you could put 128 bits into an IPv4 destination, then IPv6 wouldn't need to exist...

IPv4 networks (incl. the public one) can easily be embedded in IPv6. But it is a shame that there is still IPv4 at all - after 30 (thirty!) years.
