DNS Record Types Explained

When we open a website like google.com, we never think about how the internet finds it.

Behind the scenes, something called DNS records works silently to guide browsers, emails, and services to the right place.

But DNS sounds scary 😅

IP addresses, records, servers… it feels complicated.

So let’s break it down in the simplest way possible.

What Is DNS? (In One Line)

DNS is the internet’s address book. 📖

It converts website names into numbers that computers understand.

Imagine the Internet as a City 🏙️

Every website is a house

Every server is a location

DNS records are notes that tell how to reach the right house

Different records have different jobs.
