Cloudflare Clean IP Scanner V3.1

⚡ Cloudflare Clean IP Scanner (GUI)

A fast, single-file Tkinter desktop app that scans Cloudflare's IPv4 ranges to
find low-latency ("clean") edge IPs. Pure Python standard library — no pip
install needed.

Features

• Single-connection pipeline — one TCP socket is reused for the TCP connect,
  TLS handshake, and HTTP request. Accurate per-stage timing and ~3× fewer
  connections than the naive approach.
• Bounded concurrency — a semaphore caps in-flight work so memory stays flat
  even when scanning millions of IPs. STOP is instant.
• Lazy IP generation — ranges are streamed, never materialized into a giant
  list.
• Smooth UI — table refreshes are throttled and batched, so the window stays
  responsive at high scan rates.
• Live stats: scanned, clean, rate/s, best, avg, ETA.
• Per-IP color coding by score, sortable columns, right-click copy.
• Export results to CSV or JSON.

Run

python3 cf_scanner_gui.py

Requires Python 3.9+ with Tk support. On Debian/Ubuntu, if you hit
ModuleNotFoundError: No module named '_tkinter', install Tk:

sudo apt-get install -y python3-tk

Settings

Setting	Meaning
Port	Port to test (443 for HTTPS).
Workers	Max concurrent connections.
Timeout (s)	Per-connection timeout.
TCP trials	How many TCP connects to average for the latency sample.
IP step	Sample every Nth host (1 = scan all, higher = faster sample).
Show top N	How many of the best results to keep/render.
Max score ms	Drop results whose composite score exceeds this.
HTTP 200 only	Keep only IPs returning HTTP 200.
Require TLS	Keep only IPs that completed a TLS handshake.

Scoring

score = mean(tcp_ms [, tls_ms] [, http_ms]) over whichever stages are enabled.
Lower is better. Color: green < 60ms, light-green < 150ms, amber < 350ms, red otherwise.

Notes

This tool only measures reachability/latency to Cloudflare edge IPs. Results
depend heavily on your own network's route to each edge; an IP that is "clean"
from one network may be slow from another.

[Changelog] Version 3.1
🚀 Performance & Resource Optimization
Global Configuration Tuning: Extracted magic numbers and runtime variables into a centralized "Performance Tuning" section (MAX_WORKERS, MAX_PENDING_TASKS, QUEUE_POLL_MS, etc.) for easier maintenance and predictability.

Reduced Thread-Pool Strain: Lowered the default worker threshold from 300 to a safer, highly efficient 120. This mitigates extreme CPU context-switching and socket-exhaustion issues on lower-end systems.

Shared SSL Context Pipeline: Rewrote scan_ip() to accept an optional pre-configured ssl_ctx. Instead of spawning and compiling a heavy unverified SSL Context object inside every single thread iteration, threads now share a single global context. This significantly drops CPU overhead and prevents subtle memory leaks during massive scan operations.

Pre-compiled Request Payloads: The raw HTTP byte string sequence (HTTP_REQUEST) has been declared globally instead of being dynamically allocated inside the thread loop on every single IP check.

📊 GUI Performance & Throttling
Dual-Layer UI Throttling: Added a secondary stats timer (STATS_THROTTLE at 0.12s) independent of the main results table layout updates (TABLE_THROTTLE at 0.25s). Text metrics, counters, and progress indications are now strictly rate-limited, preventing Tkinter's text widget mainloop from freezing or lagging during rapid data drops.

🛠️ Code Quality & Robustness
Legacy Compatibility Type Hinting: Replaced native Python 3.10+ union types (dict | None) with backwards-compatible type hints via from typing import Optional and Optional[dict]. This guarantees smooth execution across older Python 3.9 environments.

Enhanced Exception Safety: Streamlined socket closing routines inside the scanning function to ensure file descriptors are reliably freed even during catastrophic socket connection drops or sudden user-initiated thread terminations.

its have bugs and problems right now .!
How to run ?
download Pydroid 3 in the Realeases its 3 apk included documents .
install them
then run the code with pydroid 3
