What this check tells you

A CNAME maps one hostname to another name. It is common for CDNs and hosted platforms, but it cannot normally coexist with other record types at the same owner name and is usually unsuitable at the zone apex without provider-specific flattening.

How to use the result

• Confirm the queried name is the exact hostname used by the affected service.
• Compare the returned values with the intended record in your authoritative DNS provider.
• Check TTL before changing records again; cached answers can outlive a rollback.
• Run the full domain report to correlate DNS with TLS, HTTP, routing, and provider incidents.

Queries use public DNS data. No account is required, and analytics never receives the domain you enter.
