What's My IP & Browser
Your IP address, location and what your browser tells every site you visit.
Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.
Your IP address
What every website can see about you
Your IP address comes from one request to our own server, which reads the address your connection arrived from and sends it straight back; no third party lookup service is used. Everything below is read from your own browser on this page. The tool saves nothing; the request only appears in the web server's ordinary access log, like any page visit.

How to use it
- Open the page: your IP address appears at the top.
- Scroll through what your browser shares with every site: language, time zone, screen, graphics card and more.
- Turn your VPN on and reload. The IP and country should change; if the time zone and language still give your real location away, adjust them.
Questions
What is an IP address?
The address the internet uses to send data back to your connection. Websites see it on every visit, and it usually reveals your internet provider and rough location.
Can a website find my exact address from my IP?
Not from the IP alone. It points to your provider and usually your city or region. Your provider knows which customer had the address at a given time.
What is browser fingerprinting?
Combining many small details a browser shares, such as screen size, time zone, fonts and graphics card, into an identifier that can recognise you without cookies.
How do I hide my IP address?
A VPN or Tor routes your traffic through another server, so sites see that server address instead of yours. It does not hide the browser details listed on this page.
About this tool
What is my IP address?
Your IP address is the address the internet uses to send data back to your connection. Every website you visit sees it, and it usually reveals your internet provider and your approximate city or region. This page shows it at the top as soon as it loads.
What else your browser gives away
Below the IP, the page lists what your browser shares with every site without asking: language, time zone, screen size, graphics card, number of processor cores and more. Combined, these details can form a fingerprint that recognises a browser even without cookies.
Checking a VPN
- Note your IP and country with the VPN off.
- Turn the VPN on and reload the page.
- The IP and country should now be the VPN server's. If your time zone and language still point to your real location, a site can notice the mismatch.
A VPN changes the address sites see, but it does not change the browser details listed here. For a fuller check, run the WebRTC leak test as well.
How it works and what is kept
To show your public address, the page makes one request to our own server, which reads the IP your connection arrived from, and the country it maps to, and sends them straight back. No third party lookup service is used, and the tool saves nothing; the request only appears in the web server's ordinary access log, like any page visit. Everything else on the page is read from your own browser.
