1.  Introduction

   This document proposes that Stateless IP/ICMP Translation for IPv6
   Data Center Environments ([RFC7755]) is advanced to Standards Track,
   following RFC6410 ([RFC6410]).

   (1) There are at least two independent interoperating implementations
   with widespread deployment and successful operational experience.

   Stateless IP/ICMP Translation for IPv6 Data Center Environments
   ([RFC7755]) has been widely implemented by at least a dozen of
   vendors and its being used in commercial deployments by hundreds of
   millions of devices.

   (2) There are no errata against the specification that would cause a
   new implementation to fail to interoperate with deployed ones.

   Stateless IP/ICMP Translation for IPv6 Data Center Environments
   ([RFC7755]) has no errata filed.

   (3) There are no unused features in the specification that greatly
   increase implementation complexity.

   There are no unused features.

   (4) If the technology required to implement the specification
   requires patented or otherwise controlled technology, then the set of
   implementations must demonstrate at least two independent, separate
   and successful uses of the licensing process.

   None.

2.  Implementation Status

   Note to RFC Editor: If this document needs to be published, please
   remove this section before publication, as it is only intended for
   the IESG evaluation.

Internet-Draft  Reclassifying SIIT-DC (RFC7755) to Stand   November 2025

   This section summarized the known status of existing and
   interoperable implementations of the protocol subject of this
   document, as well as closely related protocols.  This is following
   ([RFC7942]) and intended to assist the relevant WGs, IESG and IETF as
   a whole, in the evaluation of the document for the document progress
   through the standardization process.

   The description of the implementations does not imply any IETF
   endorsement and is solely based on public available information,
   which has not been formally confirmed by specific interoperatbility
   testing for this document publication; however, it is known to be
   confirmed by existing commercial working deployments worldwide and
   without knows interoperability issues.

   SIIT-DC: Stateless IP/ICMP Translation for IPv6 Data Center
   Environments ([RFC7755]) was originally published in February 2016.

   ([RFC7755]) is implemented together with other related protocols
   (just to name a few of the most relevant ones) such as:

   *  IPv6 Addressing of IPv4/IPv6 Translators ([RFC6052]).

   *  Explicit Address Mappings for Stateless IP/ICMP Translation
      ([RFC7757]).

   *  IP/ICMP Translation Algorithm ([RFC7915]).

   Follows a list of known implementations by different products/
   vendors, known to be mature and in production products/networks/
   services worlwide:

   *  A10.  Implemented in multiple products.

   Note that even an effort has been done to compile an extensive list
   (including a relevant URL), there may be many more implementations
   not publicly known, so this list doesn't pretent to be exclusive,
   just an indication of a sufficient number of implementations, as
   required for the evaluation of the current implementation status.
