Enterprise IPv6 Deployment Guidelines
draft-ietf-v6ops-enterprise-incremental-ipv6-02
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 potentially 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.
