How the Internet Really Works
Topic: System Administration
This live training will provide an overview of the systems, providers, and standards bodies important to the operation of the global Internet, including the Domain Name System (DNS), the routing and transport systems, standards bodies, and registrars. For DNS, the process of a query will be considered in some detail, who pays for each server used in the resolution process, and tools engineers can use to interact DNS. For routing and transport, the role of each kind of provider will be considered, along with how they make money to cover their costs, and how engineers can interact with the global routing table (the Default Free Zone, of DFZ). Finally, registrars and standards bodies will be considered, including their organizational structure, how they generate revenue, and how to find their standards.
This training is designed for beginning engineers who do not understand the operation of the Internet, experienced engineers who want to “fill in the gaps,” project managers, coders, and anyone else who interacts with the Internet and wants to better understand the various parts of this complex, global ecosystem.
What you'll learn-and how you can apply it
By the end of this webinar, participants will have a solid understanding of how the global Internet really works, who pays for what, and some of the tools available to discover information about organizations, domain names, and routes.
This training course is for you because...
- You want to understand all the pieces of the Internet, and how they work together
- You want to understand how each piece of the Internet’s infrastructure is paid for
- You want to understand how to discover information about who owns a DNS name, an IP address, or some other Internet asset
- You want to understand how the standards bodies operate, and their importance to the Internet ecosystem
