VPN & Proxy Detection - Are You Using a VPN or Proxy?
Free VPN and proxy detection tool that analyzes your connection to determine if you're using a VPN, proxy, CDN, or other network service. Learn about detection methods, accuracy limitations, privacy implications, and why false positives occur.
How This Detection Works
Detection Methods
- •ASN Analysis: Check if your traffic comes from hosting/cloud providers
- •IP Range Mapping: Compare against known datacenter ranges
- •Organization Names: Look for VPN/proxy service providers
- •Behavioral Patterns: Analyze connection characteristics
Confidence Levels
Understanding False Positives
Common False Positives
Corporate Networks
Large companies often route traffic through centralized datacenters, which can appear similar to VPN traffic.
Mobile Networks
Cellular carriers sometimes route traffic through proxy servers or optimization gateways.
Public WiFi
Hotels, airports, and cafes often use commercial internet services that may appear as hosting providers.
ISP Infrastructure
Some ISPs use cloud infrastructure or have partnerships with hosting companies for their services.
Important Limitation
This detection is based on heuristics and public information. Modern VPN services and sophisticated proxies may not be detected. This tool should not be relied upon for security-critical decisions.
Privacy & Ethics Note
Why Detect VPNs?
- •Content licensing: Geographic restrictions for media
- •Fraud prevention: Detecting suspicious behavior
- •Compliance: Meeting regulatory requirements
- •Network security: Identifying potential threats
Privacy Considerations
- •Legitimate use: VPNs protect privacy and security
- •Censorship bypass: Access to information in restricted regions
- •Public WiFi safety: Protection on untrusted networks
- •Corporate security: Remote work requirements
Our stance: We believe in privacy rights and the legitimate use of VPNs. This tool is provided for educational purposes and to help users understand how such detection works. We do not store or log detection results.
