The Reverse-DNS is a convention for components, packages, and types naming systems. A characteristic of reverse-DNS strings is that they are based on registered domain names, and are only reversed for sorting purposes. For example, if a company making a product called "MyProduct" has the registered domain name "example.com", they could use the reverse-DNS-ish string "com.example.MyProduct" to describe it.

History

Reverse-DNS first became widely used with the Java platform, and has since been used for other systems.

Examples

Examples of systems that use Reverse-DNS are Sun Microsystems' Java platform and Apple's Uniform Type Identifier.

Example of reverse-DNS strings are:

com.adobe.postscript-font (UTI string for Adobe Systems's PostScript fonts)
com.apple.ostype (UTI string for Apple's OSType)
org.omg.CORBA (Java library for CORBA)
org.w3c.dom (Java library for W3C's DOM)

-The '''reverse domain name system''', or '''Reverse-DNS''', is a system for naming components, packages, or types in computer systems. A characteristic of '''reverse-DNS''' strings is that they are based on registered [[domain name]]s, and are only reversed for sorting purposes. For example, if a company making a product called "MyProduct" has the registered [[domain name]] "example.com", they could use the '''reverse-DNS''' string "com.example.MyProduct" to describe it.
