🧠 SPG0463 Network Programming Mini Project

Network Scanner — Scan IP Range & Save Results to CSV

📘 Project Overview

This project is developed for the SPG0463 (Network Programming) mini project course at the German-Malaysian Institute (GMI).
It demonstrates a basic network scanning tool that checks a range of IPv4 addresses to determine which hosts have an open TCP port (default: port 80).
The tool uses Python’s socket module to test connectivity and stores all results in a structured CSV file.

🎯 Objectives

1. To develop a Python program that scans a user-defined IP range to identify active hosts and open ports.
2. To enhance efficiency using concurrent scanning techniques.
3. To generate a structured CSV output for easy result analysis and reporting.

🧩 Features

• User-input for Start IP, End IP, Port, and Timeout.
• Scans multiple IPs concurrently for faster execution.
• Determines if the target port (default 80) is open, closed, or unreachable.
• Measures approximate Round Trip Time (RTT) for each connection attempt.
• Automatically saves all results in a timestamped CSV file.
• Includes robust error handling and informative console output.

⚙️ Technical Details

• Language: Python 3.8+
• Libraries Used:
  • socket — for network connection handling
  • ipaddress — for generating valid IP ranges
  • concurrent.futures — for multi-threaded scanning
  • csv — for output file generation
  • datetime, time — for timestamps and performance measurement
