SIIT-DC [RFC7755] describes an architecture where IPv4-only users can access IPv6-only services through a stateless translator called an SIIT-DC Border Relay (BR). This approach has certain limitations, however. In particular, the following cases will work poorly or not at all:

       Stateless IP/ICMP Translation for IPv6 Internet Data Center              Environments (SIIT-DC): Dual Translation Mode


   This document describes an extension of the Stateless IP/ICMP    Translation for IPv6 Internet Data Center Environments (SIIT-DC)    architecture, which allows applications, protocols, or nodes that are    incompatible with IPv6 and/or Network Address Translation to operate    correctly with SIIT-DC.  This is accomplished by introducing a new    component called an SIIT-DC Edge Relay, which reverses the    translations made by an SIIT-DC Border Relay.  The application and/or    node is thus provided with seemingly native IPv4 connectivity that    provides end-to-end address transparency.

   The reader is expected to be familiar with the SIIT-DC architecture    described in RFC 7755.
