Technical Summary

   This document describes the use of the Stateless IP/ICMP Translation
   (SIIT) algorithm in an IPv6 Internet Data Centre (IDC).  In this
   deployment model, traffic from legacy IPv4-only clients on the
   Internet is translated to IPv6 upon reaching the IDC operator's
   network infrastructure.  From that point on, it may be treated
   the same as traffic from native IPv6 end users.  The IPv6 endpoints
   may be numbered using arbitrary (non-IPv4-translatable) IPv6
   addresses.  This facilitates a single-stack IPv6-only network
   infrastructure, as well as efficient utilisation of public IPv4

   The primary audience is IDC operators who are deploying IPv6,
   running out of available IPv4 addresses, and/or feel that dual
   stack causes undesirable operational complexity.  Working Group

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.

Document Quality

   The document describes something that is in fact implemented in
   at least four products from three vendors, and is in use in the
   author's networks and in other networks, as discussed at IETF
