A CAA record (Certificate Authority Authorization) is a type of DNS record that allows a domain owner to specify which certificate authorities (CAs) are permitted to issue SSL/TLS certificates for their domain. When you perform an nslookup using our CAA Record DNS Lookup tool, it queries DNS servers to retrieve the CAA records associated with the specified domain. This helps you enhance your domain's security by preventing unauthorized certificate issuance.
Simply enter the domain you wish to check, and our tool will provide you with the CAA records associated with it. This allows you to perform a comprehensive DNS lookup and ensure that your domain's certificate policies are correctly configured.
A CAA (Certificate Authority Authorization) record specifies which certificate authorities are allowed to issue certificates for a domain. By setting CAA records, domain owners can prevent unauthorized CAs from issuing certificates for their domain, enhancing the security of their website and protecting against misissuance.
Performing a DNS check for CAA records helps ensure that your domain's certificate policies are enforced, reducing the risk of fraudulent certificates and man-in-the-middle attacks.
