Reverse domain name notation
open-in-new
<a href="/facts/Wikifunctions/CIE6rUBt">Wikifunctions</a> has a function related to this topic. <p>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 <a href="/facts/Domain_name/FDLD2m5G">domain name</a> 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 <a href="/facts/Naming_collision/cLswdvPn">namespace collisions</a>, since any registered domain name is globally unique to its owner (with <a href="/facts/Alt_root/s7L2Dh1c">alt roots</a> making exceptions to this rule possible but unlikely). </p>
