Networking for Web Developers

How does the Web work? Under the hood of HTTP there's a whole stack of networking protocols.

Explore the underpinnings of the net with tools like traceroute, tcpdump, and nc.

Prerequisites and Requirements: As a beginning backend developer, you may have written code that accepts or performs HTTP requests. But you'd like to know more about what's going on "under the hood" when you use HTTP. To follow the material in this course, you'll need to enter commands into the shell and make sense of their output. You'll use command-line programs like and to gather information about computers on the network. If you're looking at this page, you pass this requirement! This course does not assume that you are configuring routers or building firewalls in your spare time. It is really intended as an introduction. If you're taking this course as part of a Udacity Nanodegree program, you can use the Linux-based development environment that we have set up for you. Many of the practical exercises in this course can be done using another Unix-like shell environment, but you may get different results for some exercises.See the for using Udacity.
