Web search engines, such as Google and Bing, are great for finding websites. But what if you're interested in finding computers running a certain piece of software (such as Apache)? Or if you want to know which version of Microsoft IIS is the most popular? Or you want to see how many anonymous FTP servers there are? Maybe a new vulnerability came out and you want to see how many hosts it could infect? Traditional web search engines don't let you answer those questions.
Following things could be searched for:
- country: 2-letter country code
- hostname: full or partial host name
- net: IP range using CIDR notation (ex: 18.7.7.0/24 )
- port: 21, 22, 23 or 80
