This document presents the address specifications and deployment
considerations of address-sharing dual stateless IPv4/IPv6
translation with prefix delegation (dIVI-pd). The dIVI-pd keeps the
features of stateless, end-to-end address transparency and
bidirectional-initiated communications of the original stateless
IPv4/IPv6 translation, while it can utilize the IPv4 addresses more
effectively. In addition, it does not require the DNS64 and ALG, and
can be used with prefix delegation.
