Mesh Networks: How They Work and Why They Matter
The internet, as most of us experience it, follows a simple model: your device connects to a router, the router connects to an ISP, and the ISP routes traffic to the rest of the world. It’s a hub-and-spoke architecture — elegant, efficient, and deeply fragile. Remove the hub, and the spokes go dark.

BGP Hijacking: How Attackers Steal Internet Traffic
The internet routes billions of packets every second across thousands of autonomous systems. At its core sits BGP — a protocol built on trust. And trust, as history shows, is easy to exploit.
What Is BGP and Why Does It Matter
The Border Gateway Protocol (BGP) is the routing protocol that makes the global internet work. Every internet service provider, cloud provider, and large enterprise operates as an Autonomous System (AS) — an independently managed network with a unique AS number (ASN).

VPN, Firewall, DDoS: What Actually Protects You Online (And What Doesn’t)
A no-nonsense guide to network security for people who don’t want a PhD to understand it.
The Internet Is a Public Road
Every time you open a browser, send a message, or use an app, your data travels across a network that was originally built for scientists to share research — not for billions of people to do their banking.

Alternative Internet Networks
The modern internet is a centralized infrastructure dependent on large ISPs, government regulation, and physical cables. However, alternative approaches to building networks offer greater resilience, privacy, or independence from traditional systems.

Bluetooth: The Wireless Technology That Connects Our World
Bluetooth is a short-range wireless communication technology that allows devices to exchange data without the need for cables or an internet connection. Operating on the 2.4 GHz radio frequency band, it enables seamless connectivity between smartphones, headphones, keyboards, medical devices, and countless other gadgets.

Infrared Data Transmission: Sending Light You Can’t See
Infrared (IR) data transmission is one of the oldest and most elegant wireless communication technologies — invisible to the human eye, yet quietly powering everything from TV remotes to industrial sensors. While it may seem overshadowed by Wi-Fi and Bluetooth today, infrared remains a remarkably capable and reliable technology with a broad range of applications.

IP Addresses: What They Are and How They Work
Every time you open a browser, visit a website, send an email, or stream a video, a complex coordination process takes place behind the scenes between millions of devices around the world. At the heart of this coordination is the IP address — a unique identifier without which the modern internet simply could not exist.
