How to Use the Proxy Checker
What does this tool check?
Our free proxy checker tests whether your HTTP, HTTPS or SOCKS5 proxies are alive and responding. For each proxy, we measure the response time in milliseconds, detect the protocol type, identify the IP geolocation (country, city, ISP), and verify authentication credentials. This helps you quickly filter out dead proxies before using them in your automation workflows.
Supported proxy formats
Enter one proxy per line using any of these formats: host:port for public proxies, host:port:username:password or username:password@host:port for authenticated proxies. You can check up to 20 proxies at once. The tool supports both IPv4 and domain-based proxy addresses.
Understanding response times
Response times below 1000ms (shown in green) indicate a fast, healthy proxy. Times between 1000–3000ms (yellow) are acceptable for most tasks. Times above 3000ms (red) suggest the proxy is overloaded or far away. For time-sensitive operations like sneaker bots or ad verification, aim for proxies under 500ms.
Why use mobile proxies?
Mobile 4G proxies from Proxy Poland use real LTE 4G/5G SIM cards, making them virtually undetectable by anti-bot systems. Unlike datacenter proxies that often get blocked, mobile IPs are trusted by platforms like Google, Facebook, and Instagram because they look identical to regular phone users. This makes them ideal for social media management, web scraping, SEO monitoring, and ad verification.
