What You Need for This Book

This publication is created to help beginners, who are already familiar with computers, to discover DNS secrets. It will be also useful for computer administrators and, specifically, for network administrators. It will be also useful as a textbook for DNS lectures.

This book discusses the fundamentals of DNS; it is not a manual for some concrete DNS implementation. It contains examples from both Windows and UNIX environments. It explains the DNS concepts to a user, independently of the hardware and software he or she uses. We can work effectively with DNS even in a not-so-powerful personal computer.
