What is the Scapy module in Python?

The Scapy module is a Python-based library used to interact with and manipulate network packets. The library is supported by both Python2 and Python3 and can be used via the command line or by importing it as a library into your Python program.

Scapy can also be run on Windows, Mac OS, and Linux systems.

Why use Scapy?

With the Scapy module, we can perform all textbook networking tasks such as scanning, probing, trace routing, and network discovery.

Scapy Can Perform All Classical networking Tasks

In addition, Scapy offers two major advantages:

  • While other network modules (such as Wireshark or Nmap) were built for specific purposes like packet sniffing and network scanning, Scapy’s functionalities can be used to build new, high-level functions as per the author’s requirement.
  • Other networking tools output filtered results by interpreting the received packets. Scapy outputs full decoded packets, leaving the interpretation up to the user.

Install Scapy

To install the Scapy module in Python3, run the following command:

pip3 install scapy-python3
