How Does Proxy Checker Work?

Proxy checker is an online program that provides proxy verification regarding server validity and anonymity.
Our tool verifies proxies in 3 simple steps:
1. Input Data: Enter up to 50 IP:Port addresses (e.g., 72.49.49.11:8080) in the text field, one per line.
2. Automated Validation: The system tests each proxy across 7 key parameters:
- Validity (Valid/Not Valid).
- Geo-Location (Country & City).
- Connection Speed (in milliseconds).
- Proxy Type (HTTP, SOCKS4, SOCKS5).
- Anonymity Level (Transparent, Low, Distorting, High).
- Special Offers — for invalid proxies, we recommend purchasing reliable proxies.
3. Results: A detailed table with instant download options: CSV and TXT formats.

  3. Prioritize High-Anonymity Proxies for confidential tasks like market research.

FAQ

How can I verify the reliability of proxies from free proxy lists before using them?

Free proxy lists often include inactive or overloaded servers. To ensure their reliability:
Copy the IP:Port entries from the list ->Test them using our Free Proxy Checker — it evaluates validity, speed, anonymity, and other key metrics ->Filter out non-working proxies and download only verified addresses.
This ensures smoother connections, even when using publicly available proxy sources.

What if a proxy is marked “Not Valid”?

Verify the IP:Port format, check firewall settings, or refresh the list — the proxy may be temporarily offline.

Can I test private (authenticated) proxies?

Yes! Use the format: ip:port:username:password for proxies requiring login credentials.
