Verify connectivity and exit IP

After you configure a proxy, run a standard check: the tunnel connects, the exit IP location matches the target, and nothing leaks your real network identity.

Three common methods:

---

Method 1: Public IP check sites (browser)

In a browser that already uses the proxy, open:

1. ipinfo.io:
   • Shows public IP, Country, City, Timezone, and Org;
   • Use it to confirm ASN for Residential or Business / ISP lines.
2. whoer.net:
   • Broader leak check: DNS location vs system timezone.
3. browserleaks.com/webrtc:
   • Checks whether WebRTC exposes your real public IP or LAN IP.

Method 2: cURL in a terminal

Use curl to test the handshake:

1. Static Proxies:

curl -x http://USERNAME:[email protected]:10001 https://ipinfo.io

2. Rotating Proxies:

curl -x http://GENERATED_USERNAME:[email protected]:9001 https://ipinfo.io

JSON with an exit IP and country means the tunnel and authentication are working.

Method 3: Proxy Tester

To batch-test many lines:

1. Open the Windows desktop app Proxy Tester;
2. Paste the proxy list into the input box;
3. Click Start Test. The tool measures latency and status on multiple threads and shows each public exit IP.

Common connection errors

• Cannot connect to the proxy server / timed out:
  • Recheck hostname and port;
  • Important: Static Proxies must use the Entry Point hostname — never the Dedicated Exit IP.
• HTTP 407 Proxy Authentication Required:
  • Auth failed. For Rotating Proxies, use the password from Users & Whitelist plus the full generated long username. For Static Proxies or Custom Proxies, confirm Username/Password, or that this public IP is on IP Whitelist.
