This book shows you how to deploy IPv6 on your network. You'll learn how to plan your' IPv6 transition, while preserving Interoperability with existing networks, how to install (if necessary), configure, test, and troubleshoot IPv6, how to. handle routing, security, and other network management issues, and how to provide standard network services, such as email and web access. The book also shows you how to adapt homegrown applications to operate over both IPv4 and IPv6. These are the hurdles that you're most likely to encounter when moving to IPv6. Making the jump doesn't cut you off from older networks-it gives you the tools you need to build a truly modern network. What is this modern network? The sky is not falling, we aren't going to run out of IP address space this year, or even next year. Everybody's reasons for deploying IPv6 are ultimately the same: to build a next-generation network that is superior to anything we have now. We need improved security, we need better ways to manage quality of service for leading-edge applications like VoIP, and we need best-of-breed network management for larger networks and increased ease of deployment for small ones. IPv6 makes it possible to solve these problems, in ways that simply aren't as straightforward with IPv4. This volume shows you how to step into the future. It distills valuable experience into something you can read and use today. It shows you how to install and configure, but more importantly, how to tbink about lPv6, and every implication of it for your network.
