Network Scanner

A small ARP network scanner that uses Scapy to discover hosts on a local network.

Purpose

• Scans an IP range and prints each discovered host's IP and MAC address.

Requirements

• Python 3
• scapy (install with pip install scapy)
• On Windows: run the script with Administrator privileges and install Npcap/WinPcap for packet sending.

Usage

1. Open a terminal in the Network_scanner folder.
2. Run:

python network_scanner.py

3. When prompted, enter the IP range to scan (CIDR notation like 192.168.1.0/24 is recommended).

Example input

• 192.168.1.0/24

Notes

• The script uses ARP requests, so it only discovers hosts on the local network segment.
• Increase the timeout in the script if you need to wait longer for replies.
