 ## DNS zone file directives
 
 A DNS zone file can be constructed using directives in addition to resource records (RRs). Directives start with `$` and are standardized - `$ORIGIN` and `$INCLUDE` are defined in [RFC 1035](https://www.rfc-editor.org/rfc/rfc1035#section-5.1), and `$TTL` is defined in [RFC 2308](https://www.rfc-editor.org/rfc/rfc2308). Additionally, BIND provides the [non-standard](https://bind9.readthedocs.io/en/latest/chapter3.html#bind-primary-file-extension-the-generate-directive) `$GENERATE` directive.
