The book consists of two parts: the first one talks about IPv6 programming, and the second one lists a number of relevant RFCs. The Programming part includes an overview of the IPv6 APIs, puts emphasis on writing address-independent programming and gives a fair number of guidelines in that area. It then describes details for porting applications to support IPv6, with details on what to look for in client and server code, followed by a number of tips for IPv6 programming. A practical example that shows how existing client and server applications (nail and popa3d) can be changed to support IPv6. The second part of the book consists of 270 (of ~360!) pages of printed RFCs, which is a bit over the top IMHO - if I'd wanted to read them I would know where to find them. On the other hand I have them all in one place, so I guess that can be excused.

Overall the book is rather technical and very much on the spot, written for people with programming and Unix background to learn on how to get the job done without much fluff. Minor nits are the long appendix and that images appear a bit blurry, but that shouldn't stop anyone from reading the book - go for it!
