Add CAA Record

What are CAA Records?

CAA (Certification Authority Authorization) records are a type of DNS record that lets domain owners specify which certificate authorities (CAs) are allowed to issue SSL/TLS certificates for their domain.

If a CA tries to issue a certificate for your domain and is not listed in the CAA record, the issuance will fail as a security precaution.
