DNS64/NAT64 for IPv6 hosts to access IPv4 websites

DNS64/NAT64 is a method of allowing IPv6 hosts to access IPv4 websites.  I find a schematic diagram to illustrate how these two systems work:

If the DNS resolves that a website has A record only, it then appends the IPv4 address of the A record to an IPv6 prefix to form the AAAA record as the destination address. NAT64 recognize that this prefix is for routing to IPv4 hosts and it knows how to extract the relevant IPv4 address for subsequent routing.

As a home user, it is not easy for me to try this set up due to the lack of NAT64 router.  The best I can play is DNS64 and by way of dig, I might try to test if an A record can be appended successfully to form an AAAA record.
