It seems pretty amazing just seeing some of the random results come up!
What I wonder, being unfamiliar how it actually works (since I don't have an account) - is the fact that my public IP comes up with 'No information available' just that no paid user has scanned it, or does it mean that my firewall is set up correctly? (I do allow ICMP but that's all for non established/related packets).
Typically it means you've configured your firewall correctly. Shodan continuously crawls the Internet so it's not based on user requesting scans. The IPv4 space is fairly small so Shodan just checks every IP (3+ billion) to find the services that run on it. Your activity/ use of Shodan doesn't affect how Shodan crawls the Internet - unless you request a scan using the API/ CLI. For more information: https://help.shodan.io/the-basics/what-is-shodan

For anyone trying to understand your foot print of internet attached devices Shodan is an invaluable resource.
It’s a great product and I’m continually amazed what the small team is able to accomplish.
