Building a Custom Ping Scanner in Python - Part 4

In this tutorial, we’ll show you how to build a simple network scanner using Python and the powerful Scapy library.

You’ll learn how to:
- Get the first three octets of an IP address from your network interface.
- Perform a ping scan on a specified IP range (from 1 to 254 in the last octet) to check which devices are online.
- Use Scapy's ICMP functionality to send pings and receive responses.
- Leverage Python's subprocess and re libraries to extract network information and automate the scanning process.

Whether you're a beginner or looking to add network scanning to your security toolkit, this project will help you get hands-on experience with Python, networking, and Scapy.

By the end of this video, you’ll be able to write your own simple network scanner that can be used for tasks like discovering active hosts or mapping your local network.
