Reverse domain name notation (or reverse-DNS) is a naming convention for components, packages, types or file names used by a programming language, system or framework. Reverse-DNS strings are based on registered domain names, with the order of the components reversed for grouping purposes. For example, if a company making the product "MyProduct" has the domain name example.com
, they could use the reverse-DNS string com.example.MyProduct
as an identifier for that product. Reverse-DNS names are a simple way of eliminating namespace collisions, since any domain name is globally unique to its registered owner.
