Although IPv6 has been deployed in a multitude of research and development networks worldwide, commercial deployment is still limited. The need for IPv6 is widely acknowledged in Asia, where IPv4 addresses are increasingly difficult to acquire. In North America, where some 74% of the allocated IPv4 addresses are located, there is not yet the sense of urgency for IPv6 as there is in Asia. Yet even here, there is growing interest and understanding IPv6 will eventually be required. It is therefore important that network operators begin familiarizing themselves with the technical issues surrounding the deployment of realistic IPv6 networks.

This tutorial provides a technical overview of the existing state of the three classes of IPv6 transition technologies: dual stacks, tunnels, and translators. Specific technologies within each of these classes are examined. Outstanding transition issues, both resolved and unresolved, are also examined. These issues include multihoming, DNS, and security.
