How to use this tool
Checks individual DNS record types, SPF TXT at the domain and DMARC TXT at _dmarc. Distinguishes missing records from lookup failures. Optional records are not universally required.
Enter the target, complete any relevant options and choose Check. Review the requested records, query outcomes and diagnostic findings. Copy Report saves the visible report.
Reading the results
No matching records and an unavailable query are different outcomes. TTLs are displayed in seconds; zero is a valid TTL. A completed request does not mean a domain passed its health checks. Only the submitted DNS owner and explicitly listed checks are inspected.
Frequently Asked Questions
Does the page name each missing DNS record?
No. The current code only lists returned records. You must compare the Type column with the records your website, email provider, or service requires.
Why is DMARC absent when TXT records are present?
DMARC normally lives at _dmarc followed by the domain. A root-domain query does not automatically request that separate hostname.
Can an absent MX row prove that the domain has no mail route?
Not by itself. General DNS queries can omit expected types. Confirm with an MX-specific lookup before deciding that the record is missing.
Why does the table say no active DNS records?
No displayable rows came back through the resolver path. Verify the name, its delegation, and the exact record owner.
Does the tool know which records my provider requires?
No. It has no provider-specific configuration list. Use the setup instructions from your hosting, email, or verification service as the comparison source.
Can caching make a removed record still appear?
Yes. A recursive resolver can keep the earlier record until its remaining TTL expires, so a stale row may persist temporarily.
