Showing my Home location

[officer]

For gaming, I was just checking my IP and normally do so by the IP Google shows. Yesterday, don't know why I scrolled down and saw few websites click on those and to my surprise they were telling my ISP, IP, Location, Web browser, and even OS? :O shouldn't all this be private? Can this information not be exploited by some evil ming people? How do they know so much information about me? Do you guys have any idea? :/

Whenever you browse at a minimum your IP address is revealed if the website in question has the technology to read it, but generally a full browser fingerprint is recorded only if you login to the site, not just land on it.
