BIND 8 is much more configurable than previous release of BIND. There are entirely new areas of configuration, such as access control lists and categorized logging. Many options that previously applied to all zones can now be used selectively. These features, plus a consideration of future configuration needs led to the creation of a new configuration file format.
A BIND 8 configuration consists of statements and comments. Statements end with a semicolon. Many statements contain a block of substatements, which are also terminated with a semicolon.
The following statements are supported:
options statements may
only occur once per configuration.
If you are performing an update installation from Tru64 UNIX Version 4.x to Version 5.0 or higher, your BIND Version 4.9.x configuration files are automatically converted to the new format.
