This beginner guide explains DNS in plain English, including what it is, how lookups work, and why websites depend on it.
Core explanation
This guide covers the basics of DNS, why it exists, how domain names get translated into network addresses, and why DNS problems can make websites seem offline.
DNS is the lookup system that helps devices find the correct IP address for a domain name.
