This article is about the Java-like naming convention. For other meanings, see Reverse DNS (disambiguation).

The Reverse-DNS is a naming convention for the components, packages, and types used by a programming language, system or framework. 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[edit]

Reverse-DNS first became widely used with the Java platform, and has since been used for other systems, for example, ActionScript 3 packages.[citation needed]

Examples[edit]

Examples of systems that use Reverse-DNS are Sun Microsystems' Java platform and Apple's Uniform Type Identifier or UTI. The Android operating system also makes use of the notation for classifying applications, as the Dalvik virtual machine made use of Java.

Example of reverse-DNS strings are:
