Stateless
Translation techniques have been gaining traction at the IETF as well as production networks. IVI is now an IETF informational RFC, where dIVI is being actively discussed. Many operators have recently submitted a motivation document to push the IETF to standardize Stateless 4v6 techniques

addresses among a set of customers (since IANA has run out of public IPv4 addresses). In parallel, it leverages IPv6 in the network in a manner that makes IPv4-customer originated traffic looks like native IPv6 traffic in the network, resulting in simplified operations. More importantly, (unlike

address sharing and dual translation. dIVI-PD is a further extension of dIVI to be well used in
Wireline (Fiber, DSL, Cable) and Wireless (3G/4G) access environment, where the prefix delegation (/64 or shorter) is preferred. dIVI-PD is now standardized as MAP-T in the IETF.

and forms IPv4-converted and IPv4-translatable addresses. The IPv4-converted IPv6 addresses are the IPv6 addresses used to represent IPv4 nodes in an IPv6 network. The IPv4-translatable IPv6 addresses are the IPv6 addresses assigned to IPv6 nodes for use with stateless

It is worth pointing out that dIVI/dIVI-PD, unlike CGN44, DS-Lite, CGN64 etc., does not require any
Stateful NAT, DNS64 and ALG in the network, thereby benefiting the network operator to not deal with any NAT logging
295:
Suffix extension enables multiple IPv6 nodes sharing a single public IPv4 address, with each node managing a different range of ports. This is achieved by defining suffix of the address format RFC6052.

in the network, thereby benefiting the network operator to not deal with any NAT logging etc. dIVI maintains end-to-end address transparency and bidirectional-initiated communications.

Dual stateless translation can restore original IPv4 address. The advantage of stateless NAT464 is that the DNS translation DNS64 and application layer gateway ALG are not needed.
