Shodan is a search engine that takes a distinct departure from most Internet search engines. Instead of searching through content intentionally served up and delivered to web browsers, Shodan allows us to search for Internet-connected devices. Created by John Matherly, Shodan uses distributed scanners throughout the world to randomly select target IP addresses and identify listening TCP and UDP ports. Listening ports are further enumerated to gather protocol banners, web pages, and other service data. All of this data is then added to an enormous, searchable database that describes the "what" of Internet devices.

This looks like it should merge with Robtex but in general it will probably make pentesters lazy when it comes to reconnaissance.  Network admins.....  "It's time to step up your game if you haven't already because now info on your systems is getting charted and searchable".
