Just Make IP4 addresses 8bytes
IPv6 is a fail. It was compromised by special interests at standards time.
Adding a class of IPv4 with 8 bytes (IPv4+4) with 0.0.0.0.IPv4 being old IPv4 addresses.
Practically no programming changes needed. and we KNOW IPv4 works and scales!
OK let IPv6 live next to IPv4+4 and see who wins
Are the router manufacturers, MS, Apple and Google brave enough? Surely its in their interests to have a working scaling Internet. Otherwise it open up the opportunity to have a "private" proprietary Internet... Oh that's their plan!...
