This article details a step-by-step approach for developing a Python script that helps identify devices connected to a Wi-Fi network. It explains the use of Address Resolution Protocol (ARP) for detecting device addresses and highlights the scapy library for creating ARP packets. The article emphasizes automating the detection of network interfaces and IP ranges using the netifaces library. Step-by-step instructions include installing necessary libraries and performing ARP scans to achieve robust network monitoring. Additionally, the article offers insights into optimizing the script for better functionality.
The Address Resolution Protocol (ARP) resolves IP addresses to MAC addresses within a local network, allowing identification of devices connected to Wi-Fi.
Using Python's scapy library, you can automate ARP scanning to discover devices in your local network, enhancing network visibility and management.
The netifaces library simplifies network interface and IP range discovery, helping to dynamically adapt the Python script to various network environments.
Installing necessary packages like scapy, netifaces, and mac-vendor-lookup is crucial for building an effective script for network device discovery.
