Its possible for you to use any domain name you want Internally as long as it isn't public. For instance, I could be using microsoft.com in my house instead of carnahan.local. If this DNS server is connected to the Internet, then you'll need to use a registered name which many companies can register for you. Godaddy is my registar, but there are probably hundreds out there. You can also use a Domain that isn't able to be used on the Internet, such as the .local that I'm using.
All you need is Bind or another dns server.
