A public IP address is a unique identifier assigned to your network by your Internet Service Provider (ISP). It's the address that websites and online services see when you connect to them, allowing data to be routed back to your device across the internet.

Knowing your public IP address is useful for: network troubleshooting, setting up remote access, configuring firewalls, gaming servers, accessing security cameras remotely, and understanding what information websites can see about your connection.

Absolutely! All IP detection happens directly in your browser through secure API calls. We don't store or log any of your IP information or location data. Your privacy is completely protected.

No, this tool only shows your own public IP address - the one assigned to your current internet connection. It cannot be used to find other people's IP addresses for privacy and security reasons.

Most ISPs use dynamic IP addressing, which means your public IP address can change periodically. This typically happens when you restart your router, after long periods of inactivity, or as part of your ISP's normal network management.
