Most helpful positive review
good material, but not for users (its for admins)

i recently wrote a review of this book on openbsd journal at [web page] overall, this is the best ipv6 book i have read so far. hagen covers the standards with clarity and skill, and presents the information well. the illustrations are pretty good at showing the structure of the packets and the formats.
ipv6 essentials does well with explaining the internals of ipv6. routing, control messages, structures, advantages. this is fantastic, and if you're looking to learn ipv6 internals or thinking about migrating a network to support ipv6, this is a great book.
however, this book isn't for a typical user of a network. if you're at home and want to start on ipv6 (ie by tunneling to the 6bone), you're going to be at a loss. this book is slim on how t get up and running on ipv6 on windows, linux, bsd, etc ... this is its biggest weakness. other weaknesses include a lack of solid material for configuring routers for ipv6 (ie QoS, the intricacies of the routing protocols and integration), migrating applications (ie DNS zones), and security (it focuses only on IPsec).
as such, i give this book a "fair" review. it's good at what it does, but it really left me wanting a lot more useful information. not a typical oreilly book (which usually focuses on actually using stuff). 3.5 stars or so ...
having spoken to the author, recently, it turns out that a detailed protocol level discussion, as opposed to implementation, was her goal. and it was well met, so i'm bumping this to 4 stars.
