                 Enterprise IPv6 Deployment Guidelines

Abstract

   Enterprise network administrators worldwide are in various stages of
   preparing for or deploying IPv6 into their networks.  The
   administrators face different challenges than operators of Internet
   access providers and have reasons for different priorities.  The
   overall problem for many administrators will be to offer Internet-
   facing services over IPv6 while continuing to support IPv4, and while
   introducing IPv6 access within the enterprise IT network.  The
   overall transition will take most networks from an IPv4-only
   environment to a dual-stack network environment and eventually an
   IPv6-only operating mode.  This document helps provide a framework
   for enterprise network architects or administrators who may be faced
   with many of these challenges as they consider their IPv6 support
   strategies.
