Aquatone

Aquatone is designed to be as easy to use as possible and to integrate with your existing toolset with no or minimal glue. Aquatone is started by piping output of a command into the tool. It doesn't really care how the piped data looks as URLs, domains, and IP addresses will be extracted with regular expression pattern matching. This means that you can pretty much give it output of any tool you use for host discovery.

IPs, hostnames and domain names in the data will undergo scanning for ports that are typically used for web services and transformed to URLs with correct scheme. If the data contains URLs, they are assumed to be alive and do not undergo port scanning.
