This site collects usage information for each HTTP or HTTPS connection. A log file entry looks like this:
18.104.22.168 - - [13/Mar/2002:22:15:32 -0500] "GET /tew/security.html HTTP/1.0" 304 - "http://www/" "Mozilla/4.78 [en] (X11; U; SunOS 5.8 sun4u; Nav)"The thing on the left there is the IP address that the connection appears to be coming from.
The information is not shared with anyone else.
If this bothers you, then you probably want to just stop using the web, because pretty much every web server on the Internet collects the same sort of information.
