Format: Paperback
Overall it was an OK book. I am already "competent" with DNS, specifically the BIND9 implementation but I got the book as reference material since the official documentation is a little sparse. The fifth edition (not sure about the others) even covers, albeit a little too briefly, how to deal with reverse lookup zones with subnet masks that do not fall on octet boundaries.

Domain Names...Serves us!
Format: Paperback
This is the most complete and must-have DNS book i've ever seen before. Nor only prepares you to understand every basic and some advanced issues about DNS, it also shows a lot of "tricks" with the most powerfull and well know - famous DNS implementation!: BIND.
If you are a beginner in the DNS world, this is a good step towards become an expert, if you're already an expert this guide will surely show you a lot of useful information in your daily DNS administration problems.
Definitely, this was one of my best investments on my way to become a site administrator.

Thicker than I anticiapted
Format: Paperback
The encyclopedia of DNS books, meaning thicker than a phone book.
I like the fact that this book is thick but so easy to read and follow along with. If you know nothing about DNS, this book makes it easy to learn about DNS. It starts with the history of DNS and then explains the hierarchy of the DNS tree. A must read if you want to improve your understanding of the internet and what happens under the hood for name resolution.

Best practical book on DNS and how it works
Format: Kindle
I was interested in finding out more about how DNS is deployed and operated in practice. The first few chapters in this book deliver very well in this regard. My motivation was to find out more about how a certain type of Internet attack -- the "open DNS resolver attack" -- works. Even though this book was written well before this attack became popular and well known -- and therefore the attack is not mentioned, let alone analyzed -- the book was still quite helpful to me.
