If you like, you can also assign aliases and add the new objects to existing groups.
Likewise, when you add or delete an object programmatically, your management
application should update the DNS database.
Changing DNS File
Names
The DNS database is composed of 16 files that each serve a particular function within
DNS. At initialization, DNS creates these files and assigns them predefined (default)
names. These default names and the content of the files they identify are listed in
Table 3-1.
