Is it possible to detect a VPN?

Yes. VPN detection works by cross-referencing an IP address against databases of known VPN providers, datacenter IP ranges, and behavioral signals. Most commercial VPN services like NordVPN, ExpressVPN, and ProtonVPN use IP ranges that are catalogued in proxy detection databases.

How do I check if an IP address is a VPN?

Enter the IP address in the input field above and click Check VPN/Proxy. The tool queries multiple detection databases in parallel and returns a merged result showing whether the IP is flagged as a VPN, proxy, or datacenter, along with a risk score and confidence level. You can also click Check My IP to test your own connection.

What is the difference between a VPN and a proxy?

A VPN encrypts all your internet traffic and routes it through a remote server, replacing your real IP with the VPN server IP. A proxy forwards specific requests through an intermediary server, usually without encryption. VPNs typically offer higher privacy and security, while proxies are faster but less secure. Both mask your real IP address, and our tool can detect both.

Can websites detect my VPN?

Yes. Websites use IP reputation databases and VPN detection services to identify VPN traffic. When you connect through a VPN, your traffic appears to come from the VPN provider IP range, which is often flagged in these databases. Websites can also detect VPNs through WebRTC leaks, timezone mismatches, and DNS leak tests. Our tool includes all of these detection methods.

How do I know if my VPN is working?

Click the Check My IP button above. If your VPN is working correctly, the results should show your VPN server IP (not your real IP), a VPN Detected status, and a high risk score. If the tool shows your real ISP and location, your VPN may be leaking or not properly connected. Run the WebRTC and DNS leak tests on this page for a complete check.

What is a risk score?

The risk score is a number from 0 to 100 that indicates how likely an IP address is to be a VPN, proxy, or anonymized connection. A score of 0 to 25 suggests a clean residential connection. 26 to 50 may indicate a datacenter or hosting IP. 51 to 75 suggests a likely proxy or VPN. 76 to 100 indicates a high-confidence VPN, proxy, or known anonymizer.

What does proxy detection mean?

Proxy detection is the process of identifying whether an IP address is acting as an intermediary server (proxy) rather than a direct user connection. Proxies can be public (open proxies), anonymous, or elite. Our tool classifies the proxy type when detected, including Public Proxy (PUB), Datacenter/Hosting (DCH), and Search Engine Spider (SES).

Is this VPN checker free?

Yes, our VPN and proxy checker is completely free with no signup required. You can check any public IP address without creating an account.

What are WebRTC and DNS leak tests?

WebRTC is a browser technology for real-time communication that can leak your real IP address even when connected to a VPN. A WebRTC leak test checks if your browser exposes your real IP through WebRTC. A DNS leak test checks if your DNS queries are sent through your VPN tunnel or if they leak to your ISP. Both tests help you verify your VPN is not exposing your real identity.

Review the results: VPN/proxy status, risk score, proxy type, and confidence level. Run the WebRTC, DNS, and timezone leak tests below to check if your real IP, DNS requests, or timezone are leaking despite your VPN being active.

What is a VPN Checker?

A VPN checker is an online tool that determines whether an IP address belongs to a VPN service, proxy server, or datacenter rather than a genuine residential connection. Our free VPN detection test tool analyzes any IP and returns a clear verdict with risk score, proxy type, and confidence level.

How VPN Detection Works

VPN detection works by cross-referencing IP addresses against databases of known VPN providers, datacenter IP ranges, and behavioral signals. Results are merged into a single, easy to understand report.

What Does Our Detection Tool Check?

Our tool checks each IP against multiple signals to determine its connection type and risk level.

VPN Detection

Identifies commercial VPN services like NordVPN, ExpressVPN, ProtonVPN, and Mullvad by checking known VPN IP ranges.

Proxy Detection

Detects public proxies, open proxies, and anonymous proxy connections that forward traffic through intermediary servers.

Datacenter/Hosting Detection

Flags IPs belonging to hosting providers like AWS, DigitalOcean, and Hetzner, often used for VPNs and proxies.

Risk Score

Calculates a 0 to 100 risk score based on detection signals, helping you assess the trustworthiness of a connection.

Proxy Type Classification

Classifies detected proxies by type, including Public Proxy (PUB), Datacenter/Hosting (DCH), Search Engine Spider (SES), Mobile (MOB) and Residential Proxies (RES).

Multi-Source Detection

Runs multiple detection databases in parallel and merges results for maximum accuracy.

VPN vs Proxy: What's the Difference?

Both VPNs and proxies mask your real IP address, but they work differently and leave different detection footprints.

	VPN	Proxy
Scope	All device traffic	Single app or browser
Encryption	Yes (full tunnel)	Usually no
Detection Difficulty	Moderate (IPs are known)	Datacenter (Low), Mobile & Residential (High)
Use Case	Privacy, security, bypass	Quick geo-unblocking

Free VPN Checker, No Signup Required

Our VPN & proxy checker is completely free with no signup, no account, and no limits. You can check any public IP address instantly. The tool runs multiple detection databases in parallel to give you the most accurate result possible at zero cost.

Trust, Quality & Data Transparency

Expertise & Experience

Network security & fraud prevention experience informs VPN, proxy, and datacenter IP detection methodology and risk score interpretation. We designed the VPN & Proxy Checker features around realistic operational workflows.

Data Sources

Multiple detection databases queried in parallel for proxy type classification, fraud score, usage type, VPN/proxy detection, and hosting/mobile flags. Results merged with confidence scoring.

Update Cadence & Quality

Databases refreshed regularly; live APIs queried on each request; detection heuristics refined continuously. The rating component reflects genuine user feedback (one rating per browser client ID) and is filtered for abuse.

Privacy & Ethics

Checked IPs are not stored or aggregated; detection runs on each request independently with no cross-user profiling. See our Privacy Policy for details. No personal account is required.
