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.

One of the best books I've read on DNS and BIND
Format: Kindle
DNS is one of those concepts that is almost kept in mystery in the tech world. The knowledge seems to be passed by word of mouth, and there doesn't seem to be one good repository to go to as an information source. That is not to say that this book is all inclusive, no book can contain every piece of knowledge you need/desire, especially on such a complex topic. This book however does a phenomenal job of demystifying the subject and giving a good, practical understanding of how DNS and BIND work.
I would highly recommend this book to anyone, whether it be the new network/sys admin who has just had complex networking needs dropped on his lap, or even the seasoned network admin who needs a good convenient reference on occasion.
