Just like the A is the first letter you learn from the alphabet, the A record will be the first DNS record you learn from the DNS. It is one of the first records that you create after creating a DNS zone, and it has a fundamental purpose. Do you want to know what it is?
What is the A record?
The A record is a DNS record that we can’t live without. Or at least the Internet won’t be possible the way we know it.
The A comes from the word address, which in this case is an IPv4 address (32-bit address). The A record is a DNS record that point to the IP address of a domain name (hostname).
When you write a domain name into your address bar, the device will search for exactly this record, so you can access the content.
