If It's Worth Doing, It's Worth Doing Right

…and this goes doubly for DNS. DNS glues the Internet together (along with several other things of course), and if you mix glue the wrong way, it won't be glue it will be goo. If you set up DNS incorrectly, a likely outcome will be service disruptions for your users, your customers, and anyone else your organization has relationships with via the Internet. And, let's face it, things such as service disruptions get noticed by users because they create unpleasant situations. The really treacherous part is that DNS problems can blindside you a week, or even weeks, after you made some unrelated change to your network.

So, pay attention to all your DNS-related work. DNS is a simple design, but many of the details in its running can foul up everything.

Together, Chapter 2, "DNS in Practice," and Chapter 3, "Maintenance and Enhancements," are the core of this book, and in one way are all you will ever need to know about DNS and BIND. However, in reality, there is a lot more to it than that, which is why this is not a 100-page booklet.
