Frequently Asked Questions
How does this proxy checker work?
We attempt a real connection through your proxy to an IP echo service. If the proxy responds, we report the external IP seen through it and the total response time. If the connection fails or times out within 10 seconds, the proxy is reported as dead.
Why is my free proxy dead?
Public free proxies are shared by thousands of users and typically die within hours. Testing shows roughly 8 out of 10 free proxies fail at any given moment. Premium proxies stay alive because providers limit users per IP and monitor them 24/7.
What protocols does the proxy checker support?
The checker supports SOCKS5, SOCKS4, HTTP, and HTTPS proxies on any port.
Is it safe to check a proxy here?
Yes. We only open a single connection through the proxy to a fixed IP echo endpoint. We do not send your data anywhere else, and we do not store the proxies you check.
