Google is a search engine for human readable content. Shodan does the same for machine readable content.
You can:
- search for specific IP addresses, and it will show you the active ports, and running services.
- search for a specific response header in the set of countries
- browse through the screenshots of open VNC & RDP
- open webcams
- and more…
The free accounts can use any feature, but the list of results is limited. But if you really want to look under the deck of the internet, the subscription is worth it.
I rarely use shodan, so I’d probably never pay for a subscription. Especially since I’ve never really hit any limit in the free plan. But I got the lifetime membership two years ago for $0.99. Even for the current $5 that’s a no brainer.
Same here and the network monitoring isn’t a bad bonus.
Whats that?
