The IESG has approved the following document: - 'SIIT-DC: Dual Translation Mode' (draft-ietf-v6ops-siit-dc-2xlat-02.txt) as Informational RFC This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-v6ops-siit-dc-2xlat/ Technical Summary This document describes an extension of the Stateless IP/ICMP Translation for IPv6 Internet Data Centre Environments architecture (SIIT-DC), which allows applications, protocols, or nodes that are incompatible with IPv6, and/or Network Address Translation to operate correctly in an SIIT-DC environment. 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 I-D.ietf-v6ops-siit-dc. Working Group Summary The only real question was whether it belonged in the WG. The WG, in discussion, determined that it constituted an operational procedure comparable to 464xlat, and was therefore within charter.
