For web teams checking a launch or tracing a fault, this test provides an immediate point of reference. See which certificate authorities a domain permits through CAA.
See which certificate authorities a domain permits through CAA. The result organizes the useful evidence so you can focus the diagnosis.
Before requesting a certificate for a domain, you check its CAA records to make sure the chosen authority is allowed. This helps avoid an issuance failure caused by a published restriction, and it gives you a clear view of the domain's current certificate policy.
The domain you enter is sent to the YOORfree server, which queries public DNS itself and returns the CAA records it finds. No file is uploaded; the request only checks the authorized certificate authorities. You can repeat the lookup whenever your certificate provider or DNS setup changes.
An empty list means that no CAA record is published for the domain. It does not automatically block an authority, but it does mean no CAA restriction is visible, so the domain relies on other controls.
Yes, it is a useful pre-check. Confirm that the intended authority appears among those allowed, then consider that authority's own rules and validation requirements before placing the order.
Enter the exact name you need to examine. A subdomain can have its own CAA records or inherit the parent domain's records depending on the DNS setup, so the answer can vary by host.
