Check if your IP is exposing any ports. If you see 404 page, nothing is exposed
For those a bit confused: This subdomain redirects to https://beta.shodan.io/host/$YOUR_REMOTE_ADDR. This runs a search against their existing database of information. Shodan has an army of bots that crawl the entire Internet and stores what it finds along the way. Folks generally pay Shodan for access to these notes.The site returns various HTTP error codes based on the results of that lookup, or shows a fancier page with open ports and other information it has on that IP address. (Example: https://beta.shodan.io/host/1.1.1.1)There is no active scan occurring here. (But you could be hinting to Shodan that these particular IPs are valid though!)
