Managing CAA Records
Table of Contents
This article describes a feature only available on newer plans.
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 don’t 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 don’t support the ability to specify via interface the destructured CAA record value representation. You can’t enter the following text:
0 issue "letsencrypt.com"
