Proxy Checker: Detect VPN & Anonymizers

Is your identity truly hidden? Our proxy checker scans 15+ HTTP headers and WebRTC signals to identify VPN usage, transparent proxies, and elite anonymizers.

AI Overview

A Proxy Checker scans your internet connection for hidden "headers" that reveal if you are using an intermediary server. It identifies whether a proxy is Transparent (leaks your real IP), Anonymous (hides IP but shows proxy use), or Elite (looks like a direct connection). Use this to verify if your VPN is actually protecting you.

Detected Proxy Headers

How Does a Proxy Checker Work?

Every time you visit a site, your browser sends HTTP headers. If you use a proxy, that server often adds its own stamps, like X-Forwarded-For or Via. Our tool on ZKB Tracking looks for these specific markers. If we find them, we know you aren't connecting directly from your home or office network.

Security Fact: Transparent proxies are the most common but offer zero privacy. They route your traffic while still including your real IP address in the data packet.

Three Levels of Proxy Anonymity

  • Level 3 (Transparent): Shows your real IP. Used by schools and workplaces for filtering.
  • Level 2 (Anonymous): Hides your IP but tells the website "I am a proxy server."
  • Level 1 (Elite): The gold standard. Hides your IP and makes your connection look like a standard home user.

Why Your VPN Might Be Leaking

Even if your headers are clean, your browser might be betraying you through WebRTC. This technology allows sites to "ask" your browser for its internal IP address, bypassing the VPN tunnel. Use our WebRTC Leak Test to ensure your browser settings are locked down.

Frequently Asked Questions

Can Netflix detect my proxy?
Yes. Netflix and banks use advanced databases to flag IP addresses that belong to data centers rather than residential homes.

Is a VPN better than a proxy?
Generally, yes. A VPN encrypts all your computer's traffic, while a proxy usually only handles your web browser traffic.

How do I get an Elite Proxy?
Most premium VPNs and "residential proxy" services offer elite-level anonymity by removing all identifying headers.
