ELI5: What can someone do with your IP address? How does it work?

The most common and easiest thing they can get is information about your physical location (city, state, ZIP code), which they can use in some cases to get even more information about you, especially if you're not careful about protecting yourself on social media websites.

Besides that, they theoretically could access your computer remotely, but there are a lot of roadblocks there, such as your ISP's internet security configuration and firewalls, your own modem and router's security configuration and your computer itself (usually has some sort of basic firewall online by default). A dedicated and capable enough hacker might be able to find a way in but it's not going to be a super simple or easy task.
