Shodan is a search engine that lets users search for various types of servers (webcams, routers, servers, etc.) connected to the internet using a variety of filters. Some have also described it as a search engine of service banners, which are metadata that the server sends back to the client.
This can be information about the server software, what options the service supports, a welcome message or anything else that the client can find out before interacting with the server.
