the structure of the DNS section

the structure of
the DNS section, which now spans almost 200 pages. It’s not only a primer on DNS; in this edition
I completely reoriented the discussion and the examples around building not just any DNS infrastructure,
but a more secure infrastructure, using split-brain DNS techniques—and if you don’t know
what that means, don’t worry, the chapter covers it all. You’ll also see in Chapters 6 and 7 that I’ve
worked hard to unify the step-by-step examples so that they all fit together, allowing you to follow
along and build a small network that is then completely ready for Active Directory…which is the next
chapter’s topic.
