4.9. Adding More Zones

Now that you have your nameservers running, you might want to support more zones. What needs to be done? Nothing special, really. All you need to do is add more zone statements to your configuration file. You can even make your primary a slave server for some zones and make your slave server primary for some zones. (You may have already noticed that your slave server is primary for 0.0.127.in-addr.arpa.)

At this point, it's useful to repeat something we said earlier in this book. Calling a given nameserver a primary nameserver or a slave nameserver is a little silly. Nameservers can beand usually areauthoritative for more than one zone. A nameserver can be a primary for one zone and a slave for another. Most nameservers, however, are either primary for most of the zones they load or slave for most of the zones they load. So if we call a particular nameserver a primary or a slave, we mean that it's the primary or a slave for most of the zones it loads.
