v2.1.2 - Bug Fix: Scan .0 and .255 Addresses

Bug Fix: Missing .0 and .255 Addresses in Subnet Scanning

Problem

When splitting large subnets (e.g. /20) into /24 ranges, the scanner used network.hosts() which silently skips the network address (.0) and broadcast address (.255) of each /24 block.

This caused valid CDN edge IPs like 188.114.98.0 (inside 188.114.96.0/20) to never be tested — reported as a GitHub issue.

Fix

Switched to list(network) which iterates all 256 addresses in a /24, including .0 and .255. CDN edge servers don't follow traditional network/broadcast address conventions, so these are perfectly valid targets.

Impact

Every /24 range was missing 2 IPs before this fix. For example, a /20 subnet (16 × /24 ranges) was missing 32 IPs total.

v2.1.1 - Config Update

What's New in v2.1.1

Config Adjustment

• Increased random_ips_per_range from 20 to 255 for wider IP coverage per /24 range during randomized scans

v2.1 - Interactive CDN Selection Menu

What's New in v2.1

Interactive CDN Selection

• Users are now prompted to choose which CDN to scan when running the script — no more manually editing config.json
• Simple numbered menu at startup:
  • 1 → Cloudflare
  • 2 → Amazon CloudFront
  • 3 → Fastly
  • 4 → All (scans all three CDNs sequentially)

Other Improvements

• Invalid input is gracefully re-prompted
• Ctrl+C is handled cleanly at the selection menu

How to Use

python cf_scanner.py

Then simply enter 1, 2, 3, or 4 when prompted.

v2.0 - Multi-CDN Support (CloudFront + Fastly)

نسخه ۲.۰ - پشتیبانی از چند CDN

ویژگی‌های جدید

• Amazon CloudFront: اسکن IP های CloudFront
• Fastly: اسکن IP های Fastly
• اسکن همزمان همه CDN ها: با تنظیم "cdn": "all"
• فایل‌های سابنت جداگانه: subnets_cloudflare.txt، subnets_cloudfront.txt، subnets_fastly.txt
• خروجی‌های جداگانه: نتایج هر CDN در فایل‌های مجزا ذخیره می‌شود

تغییرات

• subnets.txt به subnets_cloudflare.txt تغییر نام یافت
• کلاس CloudflareScanner به CDNScanner تغییر نام یافت (alias قدیمی هنوز کار می‌کند)
