Find your public IP address in one click, and see what your browser tells websites about your device: browser, operating system, screen size and time zone.
Public vs private IP
Your public IP is assigned by your internet provider and is what websites see. Your device also has a private address (like 192.168.x.x) that only works inside your home or office network.
The address comes from Cloudflare, which serves this site, so nothing is sent to a third party.
What your browser shares
Every website can read the details listed under "Your browser and device": the browser and its version, the operating system, whether it's a phone, tablet or computer, the screen and window size, your time zone and your languages. They help sites lay pages out and show local times. This page reads them in your browser only; they aren't sent to us or stored.
For example, an iPhone on Safari might show Safari 17.4, iOS 17.4, Phone, a screen of 390 × 844 (1170 × 2532 at 3×) and a time zone of Asia/Kolkata (UTC+05:30). Support teams often ask for these details, so you can copy them from here.
Frequently asked questions
Why does my IP keep changing?
Most home and mobile connections get dynamic addresses, and mobile networks often share addresses between many users.
Can someone find my home from my IP?
Usually only an approximate city or region, not an address.
Does a VPN change it?
Yes. With a VPN you see the VPN server's address.
What is my screen resolution?
The page shows it under "Your browser and device" in CSS pixels, the size websites design for, and in device pixels when your screen packs more than one pixel into each, as most phones and many laptops do. A phone that reports 390 × 844 at 3× has a 1170 × 2532 pixel panel.
Why does it say "Windows 10 or 11"?
Browsers send the same "Windows NT 10.0" text on both, so a website can only tell them apart when the browser shares extra details (Chrome, Edge and Opera do; Firefox doesn't). For the same reason Chrome on Android doesn't reveal its Android version to every page, and Macs always report an old macOS version, so the page leaves those versions out rather than guess.
