Code Examples

Frontend JavaScript Implementation
// Using fetch API
const detectVPN = async (ip) => {
  try {
    const response = await fetch('/api/vpn-detection', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ ip }),
    });
    
    const data = await response.json();
    
    if (data.success) {
      console.log('VPN Detection Result:', data.data);
      return data.data;
    } else {
      console.error('Detection failed:', data.error);
      return null;
    }
  } catch (error) {
    console.error('Network error:', error);
    return null;
  }
};

// Usage
detectVPN('8.8.8.8').then(result => {
  if (result) {
    console.log(`IP ${result.ip} is ${result.isAnonymous ? 'anonymous' : 'direct'}`);
  }
});

Rate Limits

Per IP:100 requests/hour
Burst limit:10 requests/minute
Bulk detection:100 IPs/batch
Rate limits are enforced per IP address. Contact us for higher limits.

Best Practices

• Implement proper error handling

• Cache results for repeated queries

• Use bulk detection for multiple IPs

• Respect rate limits to avoid blocking

• Validate IP addresses before sending

• Handle network timeouts gracefully

What is VPN Detection?

VPN detection is the process of identifying whether an IP address is associated with a Virtual Private Network (VPN), proxy server, or anonymization service like Tor.

Our advanced detection system analyzes multiple factors including IP reputation databases, network characteristics, and behavioral patterns to determine if your connection is anonymized.

Why Check for VPN Usage?

  • Verify your VPN is working correctly
  • Troubleshoot connection issues
  • Ensure privacy protection is active
  • Check for DNS leaks or bypasses

Frequently Asked Questions

Get answers to common questions about VPN detection, privacy, and security

How accurate is VPN detection?

Our VPN detection system achieves over 95% accuracy by combining multiple detection methods and maintaining up-to-date databases of known VPN and proxy servers.

Can this detect all types of VPNs?

We can detect most commercial VPNs, proxies, and Tor exit nodes. However, some private or residential VPNs may not be detected if they're not in our databases.

Is my data stored or logged?

We prioritize your privacy and follow strict data protection policies:

  • No IP addresses are stored or logged
  • Detection results are immediately discarded
  • All analysis is performed in real-time
  • No personal data is collected or retained
  • Zero tracking or monitoring of user activity

Why might I want to use a VPN?

VPNs provide multiple security and privacy benefits:

  • Privacy protection and anonymity
  • Secure browsing on public WiFi
  • Access to geo-restricted content
  • Protection from ISP monitoring
