## What it is
A Python CLI tool that detects and classifies Deep Packet Inspection (DPI) based internet censorship, including TCP 16-20KB connection drops, TLS/SNI blocking, HTTP blocking, and DNS hijacking by ISPs. It helps users diagnose which censorship filters their provider applies to specific domains, hostings, and CDNs.

## Use cases
- detect if my ISP blocks websites via DPI
- check why connections to CDNs drop after 16-20KB
- test whether DNS queries are being hijacked or spoofed
- find working SNI values for a hosting or CDN
- check if TLS 1.2, TLS 1.3, or HTTP access to a blocked site works
- diagnose internet censorship on my connection
- verify if my DPI bypass tool like zapret is working correctly

## When to choose
- you need to identify which censorship mechanisms (TCP RST, SNI blocking, DNS spoofing, TLS MITM) your ISP uses
- you want to test specific domains or CDN/hosting availability from your network
- you need to pick working SNI values for bypass configurations
- you want a customizable, scriptable censorship diagnostic tool

## When to avoid
- you need a censorship bypass tool rather than a detector (use zapret or GoodbyeDPI instead)
- you need censorship testing outside networks with DPI-based filtering
- you want a GUI-based testing solution
- you have active bypass tools running that would distort results
