This book is about the next generation Internet protocol. We have become familiar with the strengths and weaknesses of IPv4; we know how to design and configure it, and we have learned how to troubleshoot it. And now we have to learn a new protocol? Start from scratch? Not really. The designers of IPv6 have learned a lot from over 15 years of experience with IPv4, and they have been working on the new protocol since the early 1990s. They retained the strengths of IPv4, extended the address space from 32 bits to 128 bits, and added functionality that is missing in IPv4. They developed transition mechanisms that make IP
v4 and IPv6 coexist peacefully and that guarantee a smooth transition between the protocols. In fact, this was one of the major requirements for the development of the new protocol version.
So you do not need to forget what you know about IPv4; many things will feel familiar with IPv6. When you get started, you will discover new features and functionalities that will make your life a lot easier. IPv6 has features that you will need in tomorrow's networksfeatures that IPv4 does not provide. The day will come when our Personal Digital Assistants (PDAs) and mobile phones have IP addresses. Aside from the fact that the IPv4 address space could never cover the demand for that number of IP addresses, imagine configuring those devices with the means we have today!
One of the coolest features built into IPv6 is the autoconfiguration capability. Haven't we always struggled with IP address assignment? The advent of DHCP made our lives a little easier, but now we need to maintain and troubleshoot the DHCP servers. And when our refrigerator, our PDA, and our TV each have an IP address, will we need a DHCP server at home? Not with autoconfiguration. If you have an IPv6-enabled host, you can plug it into your network, and it will configure automatically for a valid IPv6 address. Internet Control Message Protocol (ICMP), which is a networker's best friend, has become much more powerful with IPv6. Many of the new features of IPv6, such as autoconfiguration, optimized multicast routing and multicast group management, Neighbor Discovery, path MTU discovery, and Mobile IPv6 are based on ICMPv6.
I hope that this book will help you to become familiar with the protocol and provide an easy-to-understand entry point and guide to exploring this new area.
