How do I check if I am using a proxy or VPN?

The tool above automatically detects if your connection uses a proxy, VPN, or Tor. Just load the page and it will show your connection type and anonymity level. No signup required.

Can websites detect my VPN?

Yes, websites can detect VPN usage through IP reputation databases, DNS leak detection, and WebRTC analysis. Some VPNs are harder to detect than others.

What is the difference between a proxy and a VPN?

A proxy only routes specific traffic through a different server, while a VPN encrypts all your traffic and routes it through a secure tunnel. VPNs provide better privacy and security.

What does anonymity level mean?

Anonymity level indicates how well your real identity is hidden. Transparent means your IP is visible, anonymous means your IP is hidden but proxy usage is detected, and elite means both are hidden.

Is this proxy check tool free?

Yes, this proxy/VPN check tool is completely free. No account, no signup, and no payment required. All detection runs locally in your browser.

Proxy/VPN Check

Detect whether your current IP address is associated with a proxy server, VPN, or Tor network. Check your anonymity level and connection type.

How Proxy/VPN Detection Works

Our tool analyzes your IP address against multiple data sources to determine if you're connecting through a proxy, VPN, or Tor network.

Detection Methods

IP Database Lookup: Cross-references your IP against known proxy/VPN/Tor exit node databases.
Shodan InternetDB: Checks for open ports and services commonly associated with proxy servers.
Reverse DNS: Analyzes your IP's hostname for patterns indicating proxy/VPN usage (e.g., hosting provider names).
ASN Analysis: Determines if your IP belongs to a data center or hosting provider rather than a residential ISP.
WebRTC Leak Test: Detects if WebRTC reveals a different IP address than your public IP.

Types of Proxies

HTTP Proxy: Forwards web traffic; easily detected.
SOCKS Proxy: More versatile, handles any traffic type.
VPN: Encrypts all traffic through a secure tunnel.
Tor: Routes traffic through multiple encrypted relays for anonymity.
Residential Proxy: Uses residential IPs, harder to detect but slower.

How does this tool work?

When you visit this page, the tool automatically checks your current IP address against multiple data sources. It looks up your IP in proxy/VPN databases, checks Shodan InternetDB for open ports commonly associated with proxies, analyzes your reverse DNS hostname, and examines your ASN to determine if you're using a data center or residential ISP. It also performs a WebRTC leak test to detect potential IP leaks.

Why should you check for proxy/VPN usage?

VPN verification: Confirm your VPN is working and not leaking your real IP address.
Security auditing: Detect unauthorized proxy usage on your network.
WebRTC leak detection: Find out if WebRTC is exposing your real IP despite using a VPN.
Content access: Understand why some websites may be blocking or flagging your connection.

How to protect your privacy

Use a reputable VPN: Choose a VPN provider that doesn't log your activity and offers strong encryption.
Disable WebRTC: Use browser settings or extensions to prevent WebRTC from leaking your real IP.
Use Tor Browser: For maximum anonymity, the Tor network routes your traffic through multiple encrypted relays.
Check for DNS leaks: Ensure your DNS queries are also routed through your VPN, not your ISP.
Avoid free proxies: Free proxies may log your traffic, inject ads, or serve malware.

Limitations

Proxy detection is not 100% accurate. Some VPNs and proxies are designed to evade detection, while some legitimate connections may be flagged. Results should be used as an indicator, not absolute proof.
