The proposed change enables IPv6-only nodes to reach IPv4-only services with specific non-globally reachable addresses by leveraging the Well-Known Prefix. This document updates Section 3.1 of RFC6052 ("Restrictions on the Use of the Well-Known Prefix") to allow packets in which an address is composed of the Well-Known Prefix and specific non-globally reachable IPv4 addresses to be translated.}, }
