Internet Protocols

Go beyond using browsers and learn how they actually work. Explore the inner workings of rendering engines, JavaScript execution, networking, security and performance. Discover how modern browser automation works and how AI is changing the way we interact with the web, with practical examples and insights drawn from real browser implementations.

HTTP is more than just a way to load web pages. This book takes you behind the scenes to explore how the protocol really works, from its earliest versions to HTTP/3. Learn how to read network traffic, build clients and servers from scratch, track down tricky bugs and apply what you learn to real-world systems.

Deliverability, bounces, warmup and list hygiene, measured in a real B2B sending operation. Checked against the current Resend documentation.

Learn to build, send, capture and analyze network packets with Scapy, one of Python’s most versatile networking tools. Through practical examples and runnable code, you’ll explore protocols, traffic analysis, PCAP files, custom packet creation and security testing. Whether you’re troubleshooting networks or sharpening your security skills, this book gives you the tools to get hands-on.

The internet depends on a routing system that was never built with security in mind. This book explores how BGP works, how routing attacks happen and how RPKI helps defend global networks. From protocol fundamentals to real-world deployment, it offers a practical look at the threats, tools and decisions that shape Internet routing security.

What does it really take to build a web application from the ground up, without relying on layers of frameworks to do the heavy lifting? Building Modern Web Applications in C takes you from a handful of sockets to a fully functioning, secure and production-ready web service, revealing the inner workings of HTTP, databases, sessions, TLS and everything in between. Through hands-on examples and the evolution of Taskforge, you’ll learn not just how to make a web server work but how to build one you can trust, deploy and keep running in the real world.

BGP security is more than a set of filters and policies. This book takes a practical, systems-level look at securing routing infrastructure, from RPKI and route filtering to monitoring, automation and incident response, with real configurations, code examples and lessons from incidents that have shaped how the Internet is secured.

Network traffic can look like noise until you know what to look for. This practical guide shows you how to investigate unfamiliar protocols, analyze packet captures and build reliable workflows with Claude Code. Learn to reverse engineer traffic, test your assumptions and turn raw network data into findings you can trust.

Take your IPv6 skills beyond the basics. Advanced IPv6 Engineering covers real-world network design, routing, security, automation and operations at scale, with practical examples for Linux, enterprise networks, cloud, containers and Kubernetes. Built for engineers who need to deploy, secure and manage IPv6 with confidence.

What really happens when you open a website, send a message or connect to a server across the world? This book builds the Internet from first principles, revealing how bits become packets, packets cross networks and protocols make it all work. Learn the machinery behind the Internet by understanding why each piece exists and how it fits together.
