Not sure...
Go to the command line and type:
rpm -qa | grep bind
This will run a list of all the installed rpms (rpm -qa) and it will show the results for any file that has bind in its name (grep bind). The pipe (|) allows you to join to separate commands.
If bind is installed you should see a number of files including one similar to:
bind-9.2.4-2
If bind is not installed you can install it. Just search the cd's until you locate the rpm. If you are using the GUI, double click on the file and the installation should start.
If you are using the command line, type:
rpm -Uvh /path/to/the/file
