What is a Proxy Checker?
A proxy checker tests whether an IP address operates as a proxy server, VPN endpoint, or Tor exit node. It analyzes network characteristics, open ports, and hosting data to determine if traffic from that IP is likely anonymized or relayed.
How to Use
- Enter an IP address or domain in the search box (e.g.,
1.2.3.4orexample.com:8080) - Click "Check" or press Enter to start the analysis
- Review results including geolocation, proxy detection, and open port information
