Complete Guide to Proxy Checking & Anonymity
What is a Proxy Checker?
A proxy checker is an automated testing tool that connects to proxy server endpoints (IP and port) to verify whether they accept TCP traffic, establish HTTP/HTTPS tunnels, or route SOCKS5 packets. It records latency in milliseconds and verifies if the exit IP differs from the origin.
Elite vs. Transparent
Elite (Level 1): Never leaks your IP address and sends zero proxy headers.
Anonymous (Level 2): Conceals your IP but reveals that a proxy is being used.
Transparent (Level 3): Passes your real IP in the X-Forwarded-For header, offering zero privacy.
HTTP vs. SOCKS5
HTTP/HTTPS: Ideal for web scraping, browser automation, and standard web requests.
SOCKS5: Operates at OSI Layer 5, supporting any protocol (UDP, TCP, FTP, SMTP, VoIP, gaming), lower latency, and higher flexibility for raw socket connections.
