A Beginner's Guide to Understanding DNS

Original: I Was Basically Gaslighted Into Learning DNS... and I'm Glad I Was

Short summary

A beginner-friendly explainer covering the basics of DNS (Domain Name System), comparing it to a phonebook that translates human-readable domain names into IP addresses.
