My IP Address
Run a free IP test to see your public IP address, internet provider, and network location instantly.
Detected directly from the browser via the Cloudflare network: your IP is not stored by speedtest.it.
Free public IP test
Your public IP address is the unique identifier assigned to your internet connection by your ISP. Every device on the same network shares this address when accessing the internet. This IP test runs directly in your browser via Cloudflare — nothing is stored, just like the rest of speedtest.it's tools.
IPv4 vs IPv6
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) with ~4 billion possible combinations. IPv6 uses 128-bit addresses, providing virtually unlimited addresses for modern internet needs.
Privacy considerations
Your IP address can reveal your approximate location and ISP. Using a VPN masks your real IP behind the VPN server's address. Want to check your connection speed too? Run our full speed test.
FAQ
Does my IP change when I use a VPN?
Yes. With a VPN active, this test shows the VPN server's IP address, not your real one. If the address stays identical after turning the VPN on, traffic isn't being routed through it correctly.
Is the address shown IPv4 or IPv6?
It depends on your connection: the test shows whichever address your device actually uses to reach speedtest.it — IPv4, IPv6, or both if your provider supports dual-stack.
