This book covers the next generation of the IP protocol, IPv6. Following a brief discussion on the history of the Internet Protocol (IP) the book delves into every aspect of IPv6. From IPv6 packet structure, to ARP on IPv6, to link layer encapsulation, everything is covered. Thorough understanding of networking issues under IPv4 is a prerequisite as the author warns in the preface. In most of the chapters understanding of the underlying protocols is assumed and only the changes required for IPv6 are covered. One exception to this is the chapter on routing protocols. This chapter covers the fundamentals of RIP, OSPF and BGP before explaining how IPv6 interacts with these routing protocols.

While the structure of the protocol is discussed in depth early on, in the later chapters current implementation technologies are covered. Dual stack IPv6 and IPv4 configurations as well as tunnelling IPv6 over IPv4 are presented as means of integrating IPv6 into current networks.

The book is easy to read if you have the required background knowledge. The chapters relating to IPv6 packet structure and other networking protocols can also be used a reference guide. While the chapters detailing integration with IPv4 and the hands on section do not cover the material in depth they can be used as a starting point for those who wish to know more about the area. Overall, I would recommend this book as a good first book for network specialists wishing to learn about the next generation of IP.
