The Concise Guide to DNS and BIND

Syntax

include path_name;

Definition and Usage

The include statement inserts the specified file at the point that the include statement is encountered. It cannot be used within another statement, though, so a line such as acl internal_hosts { include internal_hosts.acl; }; is not allowed.

Use include to break the configuration up into easily-managed chunks.

For example,

include "/etc/security/keys.bind"; include "/etc/acls.bind";

could be used at the top of a BIND configuration file in order to include any ACL or key information.

Be careful not to type "#include", like you would in a C program, because "#" is used to start a comment.
