Network Scanner Tool

A Python-based network scanner tool that detects live hosts, scans open ports with banner grabbing, performs GeoIP lookups, and logs/export results to CSV.

Features

• IP Range Scanning:
  Supports both CIDR notation (e.g., 192.168.1.0/24) and start-end format (e.g., 192.168.1.1-192.168.1.254) for flexible network scanning.

• Ping Sweep:
  Detects live hosts using a multithreaded ping sweep across the specified range.

• Port Scanning & Banner Grabbing:
  Scans ports (default 20–1024) on live hosts using multithreading, attempts to grab banners to identify running services, and labels known ports.

• GeoIP Lookup:
  Uses a free API (ip-api.com) to obtain geographic information (country, city, organization) for each live host.

• Logging & Export:
  Saves scan results (IP, open ports with banners, GeoIP info, and timestamp) to a CSV file in a /logs folder.

Requirements

• Python 3.6+
• See requirements.txt for Python package dependencies.
