What is this Proxy Checker?
Our bulk proxy checker is the ultimate free tool for web developers. It allows you to test hundreds of proxy servers simultaneously. Our advanced backend connects through a global CDN network to precisely determine your proxy's real exit IP, current ping latency, country, and its ISP.
Most importantly, our tool performs a deep trust check to determine if your IP address is classified as a Datacenter proxy (low trust) or a Residential proxy (high trust). Supports standard and Zennoposter proxy formats seamlessly.
