No abstract

This lack of synchronization between the end of IPv4 and the global availability of IPv6 addressing at hosts and content providers will require in some parts of the world the implementation of translation, either NAT444 or NAT64. Service Providers are preparing themselves for this scenario through the deployment of "Carrier Grade NATs". The only Preface alternative to make sure that this change in the architecture of the Internet is temporary is the deployment of IPv6. That is the challenge that this book addresses and we are happy you are joining us in this effort.
