A Record Format
The structure of an A record follows the standard top-level format definition defined in RFC 1035. The RDATA section is composed of one element:
| Element | Description |
|---|---|
| address | A 32 bit Internet address representing an IPv4 address |
The canonical representation is:
A <address>
where <address> is an IPv4 address and looks like 162.159.24.4.
For a deeper explanation of what A records are and how they work, see What Is an A Record?
In DNSimple, the A record is represented by the following customizable elements:
| Element | Description |
|---|---|
| Name | The host name for the record, without the domain name. This is generally referred to as a “subdomain”. We automatically append the domain name. |
| TTL | The time-to-live in seconds. This is the amount of time the record is allowed to be cached by a resolver. |
| Address | The IPv4 address the A record points to. |
For step-by-step instructions on creating or updating these fields, see our Managing A Records article.
