Stanford's CS144 Computer Networking course covers how the internet works, from link layer and IP through TCP and routing, and is known for hands-on lab assignments where students build a working network stack.

Commenters point to its lab assignments, which they describe as the way they worked through networking in practice.

   I agree.

   One of the best courses i had taken on Coursera was the Algorithms series by Robert Sedgewick. Apart from going through the lectures, i had obtained a great satisfaction from solving the assignments. But this year, i have taken up the lab assignments for the following: https://cs144.github.io/ https://tc.gts3.org/cs3210/2020/spring/info.html

   Both have been recommended earlier on HN.
