What is my IP address — and is it really mine?

Your current public IP address is shown in the box at the top of this page. It updates every time you load the page or press Re-check my IP. If you are connected to a VPN or proxy, you will see the VPN server’s address instead of the one your ISP assigned, and the verdict will say so.

An IP checker reports the public IP address your connection uses on the internet, then enriches it with the data attached to that address: country, city, ISP, ASN, time zone and whether it belongs to a VPN, proxy, Tor exit or datacentre. This one also runs a WebRTC leak test to catch local addresses your browser may expose.

Your public IP address is the number your internet service provider assigns to your connection so that websites and servers can send data back to you. The big number at the top of this page is the exact address every website you visit can see right now. It is shared by every device behind your router, and it usually changes when your router restarts or your ISP renews the lease.

Yes, it is completely free and needs no account. The lookup happens in your own browser: your IP is sent to the public geolocation APIs used for the analysis, and we do not run server-side logging, tracking pixels or advertising profiles on the result.

IP geolocation is an estimate, not GPS. Databases map an address block to the place where the ISP registered it, which can be the nearest large city, a regional exchange or even the ISP head office hundreds of kilometres away. Country accuracy is typically 95–99%, while city accuracy is far lower — especially on mobile networks and CGNAT connections.

Load this page with the VPN disconnected and note the IP, ISP and country. Connect the VPN, reload, and the address, ISP and location should all change and the verdict should report a datacentre or proxy IP. If your real ISP name still appears, the tunnel is leaking. Also check the WebRTC panel below — a leaked local address there can expose your network even behind a VPN.

A real (residential) IP belongs to a consumer or business ISP and points at a physical connection. A proxy or VPN IP belongs to a hosting company, so traffic appears to originate from a datacentre. Fraud systems treat the two very differently: datacentre IPs are frequently rate-limited, challenged with CAPTCHAs or blocked by streaming services and banks.

No. A public IP reveals your approximate area, your ISP and your autonomous system number. Only your ISP holds the subscriber record that ties an address to a street, and that is normally released only under a lawful request. What an IP does expose is enough for ad targeting, content blocking and rough location — which is why many people use a VPN.

Most connections are dual-stack: the ISP issues one IPv4 address (often shared through carrier-grade NAT) and a separate IPv6 prefix. Websites reachable over IPv6 see the IPv6 address, everything else sees the IPv4 one. Both are shown above so you can confirm what each type of server observes.

Residential connections are usually dynamic: the address changes when the DHCP lease expires, when the modem reboots or when the ISP re-provisions the segment — that can be hours, days or months. Business lines and servers normally have a static IP that never changes. Mobile networks can change your IP several times a day as you move between gateways.
