Some of you may have seen this pop up . Looks like a pretty cool resource.
"SHODAN lets you find servers/ routers/ etc. by using the simple search bar up above. Most of the data in the index covers web servers at the moment, but there is some data on FTP, Telnet and SSH services as well. Let me know which services interest you the most and I'll prioritize them in my scanning. "
