Understanding DNS Records
Before we get into the nitty-gritty, let's talk about DNS records. They're like the building blocks of the internet. They help turn website names into numbers that computers understand.
There are different types of DNS records:

- CNAME Record: Creates a nickname for a website
- MX Record: Tells where to send emails

Knowing these helps you use a DNS record checker better.
