We are absolutely, definitively, completely and utterly out of IPv4 addresses, warns RIPE

Re: "We have now run out of IPv4 addresses"

Protocols only work if everyone wanting to use the protocol supports it.

There isn't enough space in an IPv4 packet header for any number of extra bytes of address.

Which is why IPv6 went from 32 bit addresses to 128 bit addresses - so we are not likely to ever need a longer IPv7 address...

If you want to create your own "MyIPv4+" protocol with 64 bit addresses, you could try, but it would be a lot easier just to adopt IPv6...
