DNS and BIND (Nutshell Handbooks)

DNA and BIND discussed one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and many other services. As the authors write in the preface, if you're using the internet, you're already using DN -- even if you don't know it. However, it's one of the darker, more obscure areas of network administration. This book covers all you need to know about DNS and it UNIX implementation.
Whether you're an administrator involved with DNS on a daily basis, or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading.
