CodeAlpha_BasicNetworkSniffer.

A Python-based network packet sniffer built using Scapy to capture and analyze network traffic.

Basic Network Sniffer

📌 Overview

This project is a simple Network Packet Sniffer developed using Python and the Scapy library. It captures live network packets and displays important packet information such as Source IP, Destination IP, Protocol, Ports, and Packet Length.

This project was created as part of a Cyber Security Internship to understand network traffic analysis and packet inspection.
