NAT64 Technology: Connecting IPv6 and IPv4 Networks

Three main options are available for migration to IPv6 from the existing network infrastructure: dual-stack network, tunneling, and translation. This document briefly discusses each of these options and highlights the advantages of translation and, in particular, stateful translation, over the other two. It provides a technical overview of the translation scenarios documented in RFC 6144.

This document discusses ways to provide a seamless Internet experience to users accessing IPv4 Internet services through completely new ("greenfield") IPv6-only networks. It also describes how established content providers and content enablers can transparently provide existing or new services to IPv6 Internet users by deploying Network Address Translation IPv6 to IPv4 (NAT64) technology with little or no change in their existing network infrastructure, thus maintaining business continuity.

This is a fantastic paper - something that I don't say often - and it also is exactly the type of paper that has built the foundation of our Webtorials community over the years. As such, it provides detailed tutorial technical information that's difficult to come by in other venues.

In this case, of course, the subject matter is transitioning to IPv6 and various methods for connecting legacy IPv4 to IPv6 networks.

I'll let the paper speak for itself. And even though there are reference to Cisco's products, the paper is extremely worthwhile regardless of your exact choice(s) of supplier(s).
