Understanding different types of files when the system is booting

DNS Configuration and Data Files

In additional to file name in.named daemon, DNS on a name server consists of a boot file called named.conf, a resolver file named resolv.conf, and four types of zone data files.

You can name zone data files as long as you are internally consistent. This flexibility can cause some confusion when working on different sites or in the context of various DNS manuals and books.

For example, the file names used in the Sun Manual and most Solaris sites differ from those used in the book DNS and BIND by Albitz and Liu, O'Reilly & Associates, and both of those nomenclatures use this. There are some differences from. Public DNS Operations Guide for BIND.

In addition, this manual and other DNS documentation uses generic names that identify the main purpose of the file, and instance names specific to that file in code record samples. For example, the Solaris naming rule uses the common name host when describing the function and role of that file, and the example names db.doc and db.sales.doc in code samples.
