What are DNS A Records?

A DNS A Record is a type of address record in the Domain Name System (DNS) that points to an IPv4-formatted hostname. An A Record is one of the most common DNS records you’ll encounter, and it’s used to map your domain to its IP address.

For more information on this, check out our detailed guide on DNS A records.

Why is a DNS A record lookup useful for you?

You may be using these records to serve a variety of purposes since they are quite advantageous in the first place. This is because:

A records are easy to set up. Once you have an A record, you can use it for any domain or subdomain that points to your server. You don’t have to keep track of multiple records for each domain or subdomain—you just have one record that can handle all of them.

This is why an A record lookup can help you make sure your records are functioning as they should and are set up properly in the DNS.
