What Is My IP Address?
Your IP address (Internet Protocol address) is a unique numerical label assigned to your device by your Internet Service Provider (ISP) every time you connect to the internet. Think of it as your device's home address on the internet — websites use it to know where to send the data you request.
What Does Your IP Address Reveal?
Your public IP address reveals your approximate city and country, your internet service provider (ISP), your timezone, and whether you are connecting through a VPN, proxy, or Tor network. It does NOT reveal your exact home address, your name, or your personal information.
How To Use This Tool
This free IP lookup tool automatically detects and displays your public IP address the moment you visit this page. No signup, no download, and no personal data is collected or stored. The tool also shows your approximate location on a map, your ISP details, and runs a real-time security check to detect VPN leaks, proxy usage, and Tor exit nodes.
IPv4 vs IPv6 — Which Are You Using?
There are two types of IP addresses in use today. IPv4 addresses look like 192.168.1.1 and are the older format. IPv6 addresses look like 2001:db8::1 and are the newer format designed to replace IPv4. This tool detects and displays which version your connection is using. Most users are still on IPv4, but IPv6 adoption is growing rapidly worldwide.
Why Should You Check Your IP Address?
Checking your IP address helps you verify your VPN is working correctly, understand what information websites can see about you, troubleshoot network connectivity issues, and confirm your geographic location as seen by the internet. Security-conscious users check their IP regularly to ensure their privacy tools are functioning as expected.

Frequently Asked Questions
Everything you need to know about IP addresses and your online privacy
Your IP address is a unique numerical label assigned to your device by your Internet Service Provider (ISP). It identifies your device on the internet and reveals your approximate location. Think of it as your device's mailing address on the internet. Our tool shows your public IP address instantly when you visit this page.
An IP address reveals your approximate location — usually your city and country — but not your exact home address. Websites and services use IP geolocation for content localization, targeted advertising, and fraud prevention. Law enforcement can request your exact address from your ISP with a warrant. To hide your location, use a VPN service.
IPv4 uses 32-bit addresses (like 192.168.1.1) and supports about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (like 2001:0db8:85a3::8a2e:0370:7334) and supports virtually unlimited addresses. IPv6 was created because the world is running out of IPv4 addresses due to the growing number of internet-connected devices.
You can hide your IP address using: 1) A VPN (Virtual Private Network) — the most reliable method that encrypts your traffic. 2) A proxy server — routes your traffic through a middleman. 3) The Tor browser — routes through multiple nodes for maximum anonymity. We recommend NordVPN as it offers the best combination of speed, security, and server coverage.
Most home internet connections use dynamic IP addresses that change periodically — typically when your router restarts or your ISP reassigns them. Businesses often use static IP addresses that don't change. You can check if your IP has changed by revisiting this page. Dynamic IPs actually offer a small privacy benefit since your address changes regularly.
With your IP address, someone can: determine your approximate location, identify your ISP, send targeted advertisements, and potentially attempt DDoS attacks. However, they cannot access your personal files, passwords, or hack into your device with just an IP address. Use a VPN and keep your firewall enabled for the best protection. Check our VPN Leak Test to make sure your VPN is working properly.
