For one of the most important parts in this filed, DHCP+DDNS, the authors did not provide readers any useful syntax and examples in the very short Chapter 22. The APENDIX B "ISC DHCP Server Configuration File Reference" is also poorly written. It is not organized alphabetically, and the authors asked you to refer to the index for what you want. When I try to search the word 'ddns-domain-name', I couldn't find it in the Index. In addition, on the first page of APENDIX B, the authors gave you two broken links to make you frustrated further. APPENDIX A is "Microsoft DHCP Server Examples." Where are the examples for UNIX? We all know that configuring DHCP on NT is a piece of cake.

My general impression is that the two authors know too much theories, but seriously lack hands-on experience on TCP/IP including DHCP. The other possibility is that they don't know how to make complicated knowledge and skills simple in order to make readers understand them easily. In other words, they are not good teachers and instructors. Good teachers make complicated things simple, and poor teachers make simple things complicated.

This book should have taught you everything for setting up DHCP, but it failed. You will have to spend lots of time to search the ISC DHCP archive, and ask people the basic questions about some syntaxes. The worse thing is that this is the only DHCP book you can get on the market today. The only good thing for me was that I bought the book from an eBay auction, and did not pay the full price, $55. The value of this poorly written book is definitely not worth the high price.
