¿µ¹®³»¿ë¿ä¾à The 464XLAT architecture described in this document uses IPv4/IPv6 translation standardized in [RFC6145] and [RFC6146]. It does not require DNS64 [RFC6147] since an IPv4 host may simply send IPv4 packets, including packets to an IPv4 DNS server, that will be translated to IPv6 on the customer-side translator (CLAT) and back to IPv4 on the provider-side translator (PLAT). 464XLAT networks may use DNS64 [RFC6147] to enable single stateful translation [RFC6146] instead of 464XLAT double translation where possible. The 464XLAT architecture encourages the IPv6 transition by making IPv4 services reachable across IPv6-only networks and by providing IPv6 and IPv4 connectivity to single-stack IPv4 or IPv6 servers and peers.
