What is an IP Address?
An IP (Internet Protocol) address is a unique identifier assigned to every device connected to the internet. Think of it as your device's digital mailing address — it tells websites and services where to send data. There are two main types: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:db8::1).
Your public IP address is assigned by your Internet Service Provider (ISP) and can reveal your general geographic location. This is why many people use VPNs to mask their IP for privacy. Our IP lookup tool uses WebRTC and DNS-based detection to find your real public IP, even if you're behind a proxy or VPN.
How to Use
Simply click the "Detect My IP" button. Within seconds, you'll see your public IP address, ISP name, estimated location, and timezone. Use this information to troubleshoot network issues, verify VPN connections, or check if your DNS is leaking.
Common Use Cases
- Troubleshooting network connectivity issues
- Verifying VPN or proxy is working correctly
- Checking DNS leak status
- Identifying your ISP for tech support
- Setting up remote access or geolocation services
