Abstract

   This document provides guidance and suggestions for Internet Content
   Providers and Application Service Providers who wish to offer their
   service to both IPv6 and IPv4 customers.  Many of the points will
   also apply to hosting providers or to any enterprise network
   preparing for IPv6 users.

1.  Introduction

   The deployment of IPv6 [RFC2460] is now in progress, and users
   without direct IPv4 access are likely to appear in increasing numbers
   in the coming years.  Any provider of content or application services
   over the Internet will need to arrange for IPv6 access or else risk
   losing large numbers of potential users.  For users who already have
   dual-stack connectivity, direct IPv6 access might provide more
   satisfactory performance than indirect access via NAT.

   In this document, we often refer to the users of content or
   application services as "customers" to clarify the part they play,
   but this is not intended to limit the scope to commercial sites.
