Frequently Asked Questions
Everything you need to know about proxy testing
What types of proxies can I test with this tool?
Our proxy checker supports HTTP, HTTPS, SOCKS4, and SOCKS5 proxy protocols. Authentication with username and password is required for all proxy tests to ensure proper verification.
How fast is the proxy checking process?
Our tool can test approximately 1,000 proxies every 30 seconds, depending on the timeout settings and server response times. We process proxies in batches to ensure optimal performance.
What information does the proxy test reveal?
For each working proxy, we show the response time, geographic location (country and city), anonymity level, and connection status. Failed proxies display the specific error reason.
What do the anonymity levels mean?
High = Elite proxies that don't reveal your real IP. Medium = Anonymous proxies that hide your IP but reveal they're proxies. Low = Transparent proxies that reveal both your IP and proxy usage. Transparent = No anonymity protection.
Is authentication required for all proxy tests?
Yes, our tool requires username and password authentication for all proxy tests. This ensures comprehensive testing of proxy authentication mechanisms and provides more accurate results.
How accurate is the location detection?
We use multiple geolocation services to provide highly accurate country and city detection for tested proxies. Our system has over 95% accuracy in determining proxy server locations.
Can I test SOCKS proxies with this tool?
Absolutely! Our tool supports both SOCKS4 and SOCKS5 protocols with proper authentication handshakes. SOCKS5 proxies support full username/password authentication, while SOCKS4 uses the username as a user ID.
What makes this proxy checker different from others?
Our tool performs real network connections, authentic authentication testing, accurate geolocation lookup, and proper protocol-specific testing. Unlike simulators, we provide genuine proxy verification results.
