Learning Python Networking - Second Edition

By: José Manuel Ortega, Dr. M. O. Faruque Sarker, Sam Washington

Overview of this book

Network programming has always been a demanding task. With full-featured and well-documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be. Starting with a walk through of today's major networking protocols, through this book, you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the web. You will utilize Python for emailing using different protocols, and you'll interact with remote systems and IP and DNS networking. You will cover the connection of networking devices and configuration using Python 3.7, along with cloud-based network management tasks using Python. As the book progresses, socket programming will be covered, followed by how to design servers, and the pros and cons of multithreaded and event-driven architectures. You'll develop practical clientside applications, including web API clients, email clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.

Using Python to manipulate IP addresses and perform CIDR calculations

In this section, you will explore TCP/IP networking using Python scripts.

The Python ipaddress module

The ipaddress module simplifies working with IPv4 and IPv6 addresses in Python. In this section, we will focus on IPv4 and will work primarily with the following three class types:

  • IPv4Address: Represents a single IPv4 address
  • IPv4Network: Represents an IPv4 network
  • IPv4Interface: Represents an IPv4 interface

You can get more information about this module with the help command from the Python interpreter:

IPv4Address is the class that represents and manipulates single IPv4 addresses:

The class represents an IPv4 address or network. To create these objects...
