Professional proxy testing evaluates multiple critical aspects of proxy performance beyond basic connectivity. Our 14-test suite analyzes HTTP/HTTPS functionality, DNS leak detection, UDP support for SOCKS5 proxies, latency measurements, and OS fingerprinting.

Why comprehensive testing matters:

Verify proxy reliability before deployment
Detect security vulnerabilities and DNS leaks
Measure real-world performance and latency
Confirm SOCKS5 UDP support for gaming and streaming
Identify OS fingerprinting and privacy risks

Understanding Proxy Test Categories

Our testing suite organizes 14 tests into four categories:

Connectivity (4 tests): HTTP/HTTPS IPv4 and IPv6 connection testing
Security (4 tests): DNS leak detection (TCP/UDP) and OS fingerprinting
Performance (3 tests): Latency measurements and round-trip time analysis
Advanced (3 tests): SOCKS5 UDP support including IP detection and hostname resolution

Select individual tests or use quick presets to match your testing needs.

How to Interpret Test Results

Test results are color-coded for quick assessment:

Green (Pass): Test completed successfully, proxy working as expected
Red (Fail): Critical failure, proxy not functioning for this test
Yellow (Warning): Partial success or potential issues detected

Failed DNS leak tests indicate your real ISP may be visible. Failed UDP tests mean SOCKS5 UDP functionality is unavailable for gaming, VoIP, or streaming applications.

SOCKS5 vs HTTP Proxy Testing

HTTP/HTTPS Proxies: Run connectivity and security tests. HTTP proxies are TCP-only and don't support UDP tests.

SOCKS5 Proxies: Run all 14 tests including UDP functionality. SOCKS5 supports any protocol and is essential for:

Online gaming (low-latency UDP required)
Video streaming and VoIP applications
Torrent downloads using DHT protocol
DNS queries over UDP for leak prevention

Use the "SOCKS5 Full Suite" preset to test all 14 capabilities.

Frequently Asked Questions

How long does the full test suite take?

The complete 14-test suite typically completes in 15-30 seconds. Tests run in parallel for faster results. Individual test selection can reduce testing time to 5-10 seconds.

Why do some SOCKS5 proxies fail UDP tests?

Many SOCKS5 proxy providers disable UDP support due to infrastructure limitations or security policies. Coronium mobile proxies support full SOCKS5 UDP functionality including gaming and streaming applications.

What causes DNS leak test failures?

DNS leaks occur when DNS requests bypass your proxy and go directly to your ISP. This can happen due to IPv6 leaks, incorrect proxy configuration, or OS-level DNS settings overriding proxy DNS. Run a dedicated DNS leak test for detailed analysis.

Can I test IPv6 proxies?

Yes. Our suite includes dedicated IPv6 tests for both HTTP and HTTPS protocols. IPv6 testing verifies dual-stack proxy support and identifies potential IPv6 leaks.

What is OS fingerprinting and why does it matter?

OS fingerprinting (p0f tests) detects if your real operating system is visible through the proxy connection. This can compromise anonymity by revealing device information that should be hidden by the proxy.
