A Record
An A record (Address record) maps a domain name to its IPv4 address.

In plain English
The most basic DNS entry: it points your domain (e.g. myblog.com) to the numeric address of the server where your website lives.
A records are the most common type of DNS record. They point a domain or subdomain to a specific IPv4 address (e.g., 104.21.32.146). When you type a URL into your browser, the DNS resolver uses this record to find the server hosting the site.
If you're moving your website to a new host, you'll update the A record to point to the new server's IP. Errors in A records can lead to site downtime or 'Server Not Found' messages.
