A Python CLI tool that diagnoses whether your connection is in an RKN/TSPU-blocked zone and classifies the type of block (DNS poisoning, TCP reset, TLS SNI-based DPI, or ISP stub page) by probing each network layer independently. It probes built-in whitelist and blacklist site lists and prints a per-layer verdict with a summary.

Use cases

• check if my ISP is blocking websites via DPI
• diagnose why a site won't open in Russia
• detect DNS poisoning versus TCP reset versus TLS SNI filtering
• find out if I'm behind an RKN/TSPU censorship zone
• identify ISP stub pages that fake a successful HTTP response
• troubleshoot network blocks layer by layer
• verify which sites are blocked on my current connection

When to choose

• you need to know *how* a connection is being blocked, not just that it is
• you want a zero-config CLI that classifies censorship mechanisms automatically
• you're in or traveling to Russia and want to assess your network's filtering situation

When to avoid

• you need a general-purpose network scanner or monitoring tool
• you want to bypass blocks rather than diagnose them
• you need censorship measurement outside the RKN/TSPU context
• you require a GUI or continuous background monitoring
