Google, LLC Google, LLC This document removes the requirement introduced in Section 3.1 of RFC6052 that the NAT64 Well-Known Prefix 64:FF9B::/96 MUST NOT be used to represent non-global IPv4 addresses, such as those defined in [RFC1918] or listed in Section 3 of [RFC5735]. The proposed change enables IPv6-only nodes to reach IPv4-only services with non-global addresses by leveraging the Well-Known Prefix.
