What is CAA Lookup?

A CAA lookup refers to the process of querying the DNS system to retrieve the CAA records associated with a specific domain. It is typically done to verify which CAs are allowed to issue SSL/TLS certificates for that domain. CAA records can be used to enhance the security of a domain by restricting the CAs that are authorized to issue certificates, reducing the risk of fraudulent or unauthorized certificates being issued.

What is CAA Record Test?

CAA record test typically refers to a process or tool used to verify the correct setup and configuration of CAA (Certification Authority Authorization) records for a domain. During a CAA record test, various checks are performed to ensure that the CAA records are properly defined and that only the intended certificate authorities (CAs) are authorized to issue certificates for the domain. Some of the checks that may be performed are: Verifying that the retrieved CAA records are correctly formatted and valid, Ensuring that the CAA records have the correct syntax and are properly configured within the DNS zone file, etc.
