BIND (Berkeley Internet Name Domain) Version 8 is more configurable than previous releases of BIND. There are entirely new areas of configuration, such as access control lists and categorized logging, and you can now selectively use many options that previously applied to all zones. These features, plus a consideration of future configuration needs led to the creation of a new configuration file format.
A BIND 8 configuration file consists of statements and comments. Statements end with a semicolon. Many statements contain a block of substatements, which also end with a semicolon.
The configuration file supports the following statements:
options statements can occur only
one time in a configuration file.
If you are performing an update installation to Tru64 UNIX Version 5.0, your BIND Version 4.9.x configuration files are automatically converted to the new format.
