Have you looked at RFC2606/BCP32 "Reserved Top Level DNS Names"?  
That document says that the top level domains 
".test",".example",".invalid" and ".localhost" are reserved for 
testing adn documentation purposes and will not be used later.  In 
addition it has also specified that the second level domains:  
example.com, example.net, and example.org are also reserved for 
testing and internal use only.
