What information does my IP address reveal?
While there isn't much the average curious person can find out about your online activity through your IP address, your personal information isn’t entirely safe from websites you visit.
If you were to send an email from your home or office, a person with savvy internet skills (e.g. a hacker) and the right tools can use your exposed IP address to find out (with good accuracy) the approximate location it was sent from.
Moreover, your personal information can be tracked by third parties like your ISP, advertisers, hackers and even government agencies.
In the case of cybercrime, law enforcement authorities might obtain a subpoena to enable them to track a user through their IP address.
In that instance, they can take that IP address to the ISP to get more information about the user like legal name and home address.
