The Domain Name System (DNS) is a fundamental part of the internet, providing a way to match domain names (such as `example.com`) with the numerical IP addresses that computers use to connect to each other.
DNS is used by everyone who accesses the internet, making it one of the most critical components of the internet infrastructure.
Here are a few most common ones.

1️⃣ A DNS record
