IPv4ES the ultimate solution combining best parts of the both worlds!
Initial worlds: I've seen so much denial and whining about IPv6. People just want IPv4 with more addresses. There's the solution.
People absolutely hate:
Colons and letters in the addresses.
Complex and long hex addresses (ie. letters) with colons.
Design goals:
Require minimal changes to the user interfaces and existing processing logic.
Keep the IPv4 address format, which is familiar and loved by users and administrators.
Use widely supported underlying stack allowing extremely fast adoption.
Extend the IPv4 style compatible address address space drastically.
How can we accomplish all that?
Address format is N.N.N.N, but with with 32 bit unsigned integers instead of old 8 bits. As result, we've got a plenty of address space.
Utilizing underlying widely supported technical networking stack with 128 bit address space of the box. Making adoption easy and fast.
Output from following Python class:
IPv6 ::1 as IPv4ES 0.0.0.1
IPv6 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff as IPv4ES 4294967295.4294967295.4294967295.4294967295
IPv4ES 255.512.65535.4294967295 as IPv6 0:ff:0:200:0:ffff:ffff:ffff
IPv6 2001:db8:dead:beef:cafe:bab3:1337:c0de as IPv4ES 536939960.3735928559.3405691571.322420958
The Python class including the address handler and conversion. This is a light PoC so there's no proper exception handling and or validation. All inputs to the class are expected to be mostly valid.

Slogan, sometimes you'll need just a silly solution for bonkers people.
