Reverse domain name notation
The reverse domain name system (reverse-DNS), sometimes confused with Reverse DNS lookup or Reverse domain hijacking, is system for naming components, packages, or types in computer systems. A characteristic of reverse-DNS strings is that they are based on registered domain names, only are 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.
History
Reverse-DNS first became widely used with the Java platform, and has since been used for many other systems.[citation needed]
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'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)
