Understanding Your Digital Footprint: IP and Browser Diagnostic
Every time you visit a website, your browser shares a multitude of technical data. This dashboard aggregates this information to help you understand what servers see about you.
Why check your IP address and browser details?
- Security and Privacy: Check if your VPN is actually working. Our WebRTC leak test reveals if your local (internal) IP address is exposed despite using a secure tunnel.
- Technical Support: If you encounter a bug on a site, developers need to know your precise browser version, OS, and screen resolution. Use our "Support Report" button to copy a ready-to-use data sheet.
- Digital Fingerprinting: Even if you block cookies, sites can identify you via your "Fingerprint". It's a unique signature based on your hardware (GPU), system fonts, and software configuration.
Technical details explained
- Public vs Private IP: Your public IP is your address on the global web. Local addresses (e.g., 192.168.x.x) are only visible on your Wi-Fi network, except in the case of a WebRTC vulnerability.
- GPU and Rendering: We use WebGL to identify the exact model of your graphics card. This data is often used for advertising profiling because it varies little between sessions.
- User-Agent: This is the "ID card" your browser sends with every request. It contains the name of the rendering engine (Blink for Chrome/Edge, Gecko for Firefox) and your system version.
Frequently Asked Questions
Q: Is My Browser & IP Details free to use?
R: Yes, the My Browser & IP Details utility is 100% free. All tools on Dolf.in are accessible at no cost and without intrusive ads.
Q: Is my data secure?
R: Absolutely. Dolf.in uses a 'Serverless' approach: your data is processed locally in your browser and is never sent to our servers.
Q: Do I need to install any software?
R: No, no download or installation is required. Everything works directly in your web browser.
Q: What is the difference between my public IP and my local IP?
R: Your public IP is the address by which you are identified on the global Internet by websites and services. Your local IP (displayed via the WebRTC test) is the address used only within your home or business network (e.g., 192.168.x.x).
Q: Why is my geolocation not exact?
R: IP geolocation relies on ISP databases. It usually indicates the data center or routing node closest to you, not your precise physical address, for privacy and network structure reasons.
Q: What is digital fingerprinting?
R: Digital fingerprinting is a technique used to uniquely identify a user by combining many factors: screen resolution, installed fonts, GPU hardware, and browser version. Even without cookies, it sometimes allows you to be tracked across the web.
