If one end is behind a NAT64 and there is no mechanism for discovering the NAT64's IPv6 interface prefix and mapping algorithm (and at present there is not), there is no way to send IPv6 IP packets from the IPv6-only host to IPv4 literal addresses (that is to say, addresses learned via a mechanism other than DNS responses synthesized by the DNS64 part of the NAT64 "solution") on the IPv4 Internet through said NAT64.
While a rather inelegant solution, it just popped into my head that one could do an AAAA query for a known-value A record (i.e., under skype.com), and based on a response (if any), replace the known IP value with the IP which with one wants to connect. A little weird, but it's a thought. Jima
