Abstract

Historically, dual stack [RFC4213] [RFC6883] has been the recommended way to transition from a legacy IPv4-only environment to one capable of serving IPv6 users. However, for IDC operators, dual-stack operation has a number of disadvantages compared to single-stack operation. In particular, running two protocols rather than one results in increased complexity and operational overhead with little return on investment for as long as large parts of the public Internet remains predominantly IPv4 only. Furthermore, the dual- stack approach does not in any way help with the depletion of the IPv4 address space, which at the time of writing is a pressing concern in most parts of the world.

 SIIT-DC: Stateless IP/ICMP Translation for IPv6 Data Center Environments

Abstract

   This document describes the use of the Stateless IP/ICMP Translation    Algorithm (SIIT) in an IPv6 Internet Data Center (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 utilization of public IPv4 addresses.

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