From packets to pixels: how the internet actually works

This article offers a comprehensive, hands-on explanation of the internet's fundamental workings, written by an engineer who maintains API tools. It covers the path from a keystroke to a rendered webpage, including what packets are, why bare domains can't be CNAMEs, the reality of DNS propagation, and where browsers spend time between receiving bytes and displaying pixels. The author corrects common misconceptions and provides terminal/browser exercises to verify each concept. It's ideal for developers who want to solidify their understanding of networking basics.
