What is my IP address?
FastIPInfo shows your public IP, geolocation, ISP, device, connection and privacy exposure in one place — instantly, privately, and entirely in your browser.
Your complete IP & network snapshot
Every device on the internet has a public IP address — a numeric label your internet provider assigns so that websites, apps and game servers know where to send data back. The moment you load a page, that address (and a surprising amount of context around it) becomes visible to the other end. FastIPInfo gathers all of it on one screen so you can see exactly what you are sharing.
Unlike most "what is my IP" sites, every check here runs client-side in your browser. We don't run trackers on your results, we don't build a profile, and we don't store your address. The only network call we make is to a public IP-geolocation API to translate your address into a city and ISP — the rest (browser, device, connection and privacy data) is read directly from your own browser.
IP address & location
Everything a website learns the moment you connect, sourced from public IP intelligence.
Location is derived from your IP and is approximate (typically city- to region-level). It is never your exact GPS position.

What is my IP address used for?
Your public IP address routes internet traffic back to your network, lets services apply rough geo-restrictions, helps detect fraud, and is logged by most websites you visit. It identifies your network — not you personally — but combined with other data it can narrow down who and where you are.
Is the location shown my exact address?
No. IP geolocation maps your address to your ISP's nearest registered point of presence. It is usually accurate to the city or region, occasionally only to the country, and is sometimes tens of kilometres off. It cannot reveal your street address.
Why is my IP different from a friend's on the same Wi-Fi?
Devices behind the same router share one public IPv4 address but each has a private local address (like 192.168.x.x). If your network also has IPv6, each device may show its own public IPv6 address. A VPN or mobile data connection will also change the public IP entirely.
Does FastIPInfo store or sell my data?
No. There are no accounts, no logging of your IP, and no selling of data. All detection runs in your browser and results are shown only to you. See our privacy policy for details.
How do I hide or change my IP address?
Use a reputable VPN or the Tor Browser to route traffic through another server, switch between Wi-Fi and mobile data, or restart your router if your ISP assigns dynamic addresses. After connecting, reload this page to confirm the new address and run the WebRTC leak test to be sure nothing is leaking your real one.
Check any IP address, not just your own
