This course provides a practical introduction to the Border Gateway Protocol (BGP), the routing protocol that enables communication between networks across the Internet. Starting with the fundamental concepts of IP prefixes and Autonomous Systems, learners will explore how BGP exchanges routing information, how routers establish neighbor relationships, and how routes are propagated between networks.
The Internet is becoming a bigger target than ever for attacks. Attacks will continue to strike, and a single attack can dramatically slow down the Internet. Learn more about how Blackholing at Internet Exchanges can stop the malicious traffic.
This module serves as an introduction to data centers: what they are, how they power our digital world, key terms and definitions, the people and processes behind them, and more. It provides the essential foundation needed to build your understanding as you explore deeper into the industry.
The internet is not a single system, but a layered environment where infrastructure, protocols, services, and people interact. This course explains how these layers connect and how cooperation between technical communities, governments, companies, and civil society helps maintain an internet that remains open, secure, and accessible to everyone.
This course introduces the technical building blocks that make the internet work at global scale. It explains how standards, identifiers, names, numbers, and regional registries create a shared system that allows billions of devices and networks to connect, communicate, and grow reliably.
Behind the internet’s daily operation lies a complex system of coordination between technical communities, organizations, businesses, and public institutions. This course explores how governance models, cybersecurity frameworks, shared protocols, and global agreements help keep digital networks secure, resilient, and interconnected.
