Network Scanner

Introduction

The Network Scanner is a Python script that scans a specified IP range for active devices on the network. It uses ARP requests to discover devices and retrieves their MAC addresses. Additionally, it can query an external API to provide vendor information based on the MAC address. The script also detects and displays the operating system of each scanned device using the nmap library.

Features

• Scans a specified IP range for active devices.
• Retrieves the IP and MAC addresses of detected devices.
• Optionally fetches vendor information based on MAC addresses using an external API.
• Detects and displays the operating system of each device.
• Simple command-line interface for ease of use.

Requirements

To run this script, you need the following:

• Python 3.x
• The scapy library for packet manipulation.
• The requests library for making HTTP requests.
• The python-nmap library for OS detection.
