Operational Guidance for IPv6 Deployment in IPv4 Sites using ISATAP
draft-templin-v6ops-isops-15.txt
Abstract
Many end user sites in the Internet today still have predominantly
IPv4 internal infrastructures. These sites range in size from small
home/office networks to large corporate enterprise networks, but
share the commonality that IPv4 continues to provide satisfactory
internal routing and addressing services for most applications. As
more and more IPv6-only services are deployed in the Internet,
however, end user devices within such sites will increasingly require
at least basic IPv6 functionality for external access. This document
therefore provides operational guidance for deployment of IPv6 within
predominantly IPv4 sites using the Intra-Site Automatic Tunnel
Addressing Protocol (ISATAP).

Internet-Draft ISATAP Operational Guidance April 2012
1. Introduction
End user sites in the Internet today currently use IPv4 routing and
addressing internally for core operating functions such as web
browsing, filesharing, network printing, e-mail, teleconferencing and
numerous other site-internal networking services. Such sites
