The IPv6 address format uses hex, that is always going to be shorter than decimal. I like that it is fixed width, has zero compression, and is distinct from IPv4.

It is physically impossible for IPV4 32-bit addresses to access IPv6 with 128-bit addresses. Accessing IPv4 from IPv6 requires middleware to translate IPv6 to IPv4 and IPv4 response back to IPv4. That is NAT64.
