The IESG has received a request from the IPv6 Operations WG (v6ops) to consider the following document: - 'SIIT-DC: Dual Translation Mode' <draft-ietf-v6ops-siit-dc-2xlat-01.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-09-22. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-v6ops-siit-dc-2xlat/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-v6ops-siit-dc-2xlat/ballot/ No IPR declarations have been submitted directly on this I-D.
