How Our Proxy Checker Works
Checking proxies shouldn't be complicated. Our free proxy checker online utility allows you to instantly validate whether an IP is alive, determine its response time, and confirm its anonymity—all with no login required.
When you initiate a test, our server-side checker will securely ping a neutral target to evaluate your proxy. We utilize parallel processing so this bulk proxy checker can test multiple addresses simultaneously without freezing your browser.
Key Metrics Evaluated
- Status: Confirm if the proxy is online (Dead or Alive).
- Latency: Perform a proxy checker latency test to measure the Round Trip Time (RTT) in milliseconds.
- Anonymity: Ensure your IP acts as an Elite, Anonymous, or Transparent proxy without revealing your real IP address.
How to Test Proxy Speed
Many users wonder how to test proxy speed. Speed is heavily dependent on the type of proxy you are using and its geographic proximity to the target server.
If you're noticing high latency on your current IP, this proxy tester will flag it with a red status. Consider upgrading to a premium datacenter proxy which offers dedicated gigabit speeds compared to over-saturated public proxies.
Why Proxy Not Working Fixes
Why is your proxy not working? The most common reasons include:
- IP Ban: The target website has banned the server. Switch to a residential rotating network to bypass filtering.
- Authentication Issue: Ensure your username and password are correctly formatted (`IP:Port:User:Pass`).
- Wrong Protocol: Attempting to route HTTP traffic through a strictly SOCKS5 port will fail. Ensure you check SOCKS5 proxy online properly.
