In Chapter 1, Active Directory Fundamentals, we looked into domain trees and explored how they can be used to organize the domain structure in the hierarchical method. DNS allows you to translate that logical structure into the domain namespace. Similar to a tree, it starts from the root and is spread into different layers, such as branches and leaves.
