FYI: Shodan also does monthly hostname-based scans of the Internet where we set the "Host"/ SNI headers. We use our own DNS DB to grab a list of hostnames/ IPs to launch scans of:
https://www.shodan.io/domain/ycombinator.com https://www.shodan.io/domain/ycombinator.com
At the moment, I think we're checking around 600 million hostnames.

- achillean 5y agoYes, via the API. Btw all of our websites are entirely built on the same public Shodan API that everybody else has access to.
