Running IPv6

Running IPv6 explains how to install and operate the IPv6 protocol for Windows XP, Mac OS X, FreeBSD, Red Hat Linux, and Cisco routers. The book also covers DNS and BIND, Zebra, Apache 2, and Sendmail. While IPv4 uses 32-bit addresses, IPv6 addresses are 128 bits long, and allow for more unique addresses. While the adoption of IPv6 won't be immediate, it is necessary.

Running IPv6 compares and contrasts IPv6 to IPv4, and discusses the advantages and disadvantages of each. Because most major software and hardware vendors have adopted IPv6, the focus of this book is to leverage your existing knowledge of IPv4 and to help you apply that knowledge to the newer protocol.
