Managing CAA records

Table of Contents


This article describes a feature that is only available to the new plans.

You can manage CAA records in DNSimple using the DNS record editor.

The instructions in this article assume you’re familiar with the CAA record format and usage.

CAA records are only supported on the DNSimple primary name servers (ns1.dnsimple.com through ns4.dnsimple.com). We do not support transferring CAA records to secondary name servers.

Standard mode vs Custom mode

The DNSimple interface allows you to manage CAA records using two different modes:

  • the standard mode provides a pre-populated interface to help enter the appropriate values for the CAA record. allows you to create a CAA record to whitelist a certificate authority. allows you to create a CAA record to specify the email for reporting policy violations.
  • the custom mode () allows you to modify the CAA record tag/value values directly.

We do not support the ability to specify via interface the destructured CAA record value representation. In other words, you cannot enter the following text:

0 issue "letsencrypt.com"

Add a CAA record

To add a CAA record to whitelist a Certificate Authority

  2. Select the tab.

  3. Enter the CAA record information.

    • Name: the subdomain you want to create the record for, without the domain name. For example, if you want to represent www.example.com enter www. Leave it blank to represent the root domain example.com.
    • Provider: the Certificate Authority you want to allow.
    • Certificate type: the type you want to allow.

    As with any other DNS record, you can configure:

    • TTL: the record time-to-live.

    Once you’re ready, click to confirm and create the record.

  4. The record is created and visible in the record list.
