I am currently working through a DNS book and reading the chapter about configuring a zone through the Configure DNS server Wzard. I'm ok about Forward and Reverse lookup zones. What I'm not sure about are the zone(s) themselves. Do I need to set-up at least one zone, does it depend on how I want my home network to develop, does it matter what I call them as long as they end in .com? Are they essential if I want to install Active Directory, which I still want to do?
I don't want to rush through all this in case I encounter problems later. Books tend to show you what you can do and not always why you would need to!
