This insightful volume covers IPv6 in detail and explains
all the new features and functions. Aimed at a broad range of professionals,
including system and network administrators, engineers, network designers,
and IT managers, IPv6 Essentials is for anyone who wants to understand
how to plan for, design, and integrate IPv6 into a current IPv4 infrastructure.
The book explains the functionality of IPv6 by discussing the IPv6 header,
ICMPv6, autoconfiguration mechanisms, IPv6 routing protocols, interoperability
and transition mechanisms and last but not least includes a chapter that
explains how to get started on different operating systems.

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 to troubleshoot it. And now we have
to learn a new protocol? Start from scratch? Not really. The designers
of IPv6 have learned from over 15 years of experience with IPv4 and they
have been working on the new protocol since the early 90s. They retained
the strengths of IPv4, extended the address space from 32-bits to 128-bits,
and added functionality that we are missing in IPv4 today. They developed
transition mechanisms that make IPv4 and IPv6 coexist peacefully and that
guarantee a smooth transition. In fact this has been one of the major
requirements for the development of the new protocol version. This book
covers all you need to know to become familiar with IPv6 - you will love
read this book?
This book covers a broad range of information about IPv6 and is an excellent
resource for anybody who wants to understand or implement the protocol.
This book is for system and network administrators, engineers, network
designers, and IT managers. If you need to plan your corporate strategy
for IPv6 you will be most interested in chapters 1, 4, 9 and 10. If you
are a system or network administrator, all chapters are relevant: this
book provides a foundation for IPv6 implementation and integration with
IPv4. If you manage the infrastructure in your company you will especially
be interested in the Chapters 7 and 8, which cover Layer 2 issues and
routing, and Chapter 10, which addresses interoperability.
Content at a Glance
Chapter 1, IPv6 versus IPv4
This chapter shortly explains the history of
IPv6, gives an overview of the new functionality and describes some
live test- and production-networks that are already using IPv6.
||Chapter 2, The Structure
of the IPv6 Protocol
This chapter describes the new IPv6 header format, with a discussion
of each field and a trace file example. It also describes what Extension
Headers are, what types of Extension Headers have been defined, and
how they are used.
||Chapter 3, IPv6
This chapter explains everything you need to know about the new address
format, address notation, address types, international registry services,
and prefix allocation.
||Chapter 4, ICMPv6
This chapter describes the new ICMPv6 message format, the
IMCPv6 Error messages and available Informational Messages, the ICMPv6
header in a trace file, and discusses the extended functionality based
on ICMPv6 such as Neighbor Discovery, Autoconfiguration, Path MTU
Discovery, and Multicast Group Management. You will learn how ICMPv6
makes administration easier.
||Chapter 5, Security
This chapter begins with a short discussion of basic security concepts,
requirements, and current solutions. It then covers the IPSEC framework,
security elements available in IPv6 for authentication and encryption,
how they are used and how they integrate with other elements such
as NAT routers and autoconfiguration.
||Chapter 6, Quality
of Service in IPv6
This chapter discusses basic requirements and types of QoS. QoS elements
available in IPv6 and how they can be implemented are explained. It
also describes different QoS architectures and introduces further
work in this area, primarily on resource reservation.
||Chapter 7, Networking
This chapter discusses Layer 2 support for IPv6 (Ethernet, Token Ring,
ATM, Frame Relay etc), explains multicast support and multicast routing,
Mobile IPv6, and discusses some sample network designs that show how
IPv6 can grow into our networks step-by-step without interruption
of our IPv4 services.
||Chapter 8, Routing
This chapter discusses the advanced routing features with IPv6 and
covers the available routing protocols such as RIPng, OSPFv3 for IPv6,
BGP extensions for IPv6, IS-IS, and EIGRPv6.
||Chapter 9, Upper
This chapter discusses what is going on above the IP layer, starting
with changes for TCP and UDP, and continuing with DHCPv6, DNS extensions
for IPv6, SLPv2 in IPv6 networks, FTP, Telnet and Web servers.
||Chapter 10, Interoperability
This chapter discusses the different transition mechanisms that have
been defined, such as dual-stack operation, tunneling and translation
techniques, and shows how they can be used and combined in order to
ensure peaceful coexistence and smooth transition. It also provides
a list of vendor links to find out what equipment, stacks and software
is available currently.
||Chapter 11, Get
your Hands Dirty
This chapter explains how to get started with IPv6 on different operating
systems such as Sun Solaris, Linux, Windows 2000 and Windows XP, and
on a Cisco router. It also explains what I did in my lab and provides
examples of trace files.
The Appendix gives a short introduction
to the RFC process and authorities, and provides a list of relevant
RFCs for IPv6. The Appendix reflects the chapter organization of
the book and provides summaries of all indexes, protocol numbers,
messages types, address allocations. The Appendix is your best place
for getting quick information if you are configuring or troubleshooting
