Now that you have your name servers running, you might want to handle more zones. What needs to be done? Nothing special, really. Just use the DNS console to select the appropriate server in the left pane, then choose Action → New Zone.... Follow the instructions earlier in this chapter according to whether you are creating a primary or a slave (secondary) zone.
At this point, it’s useful to repeat something we said in an earlier chapter. Calling a given name server a primary master name server or slave name server is a little silly. Name servers can be authoritative for more than one zone. A name server can be a primary master for one zone and a slave for another. Most name servers, however, are either primary master for most of the zones they load or slave for most of the zones they load. So if we call a particular name server a primary master or a slave, we mean that it’s the primary master or a slave for most of the zones it loads.
