Adree on better doing single-stack right. But why DNS64 over PREF64? AIU, a system resolver can provide all the translated answers by processing PREF64 after having validated DNSsec (including sensible results for getaddrinfo(AF_INET6, "1.2.3.4", ...)), and applications that do everything in userspace won't get the benefits of DNS64 either (typ. because of their 8.8.8.8 DoH server).
