This plugin tries to find out if the web application under test is stored in a shared hosting.
The procedure is pretty simple, using bing search engine, the plugin searches for "ip:1.2.3.4"
where 1.2.3.4 is the IP address of the webserver.
One configurable option exists:
- resultLimit
Fetch the first "resultLimit" results from the "ip:" bing search.
