How it works
Queries Cloudflare’s public DNS resolver for six record types. Results include time to live and distinguish no records from a failed resolver request.
- Enter the domain or subdomain to investigate.
- Look up records and compare them with your provider’s settings.
- Allow for DNS caching after changing a record.
Is this tool free to use?
Yes. No account is required; reasonable request limits keep public lookups available to everyone.
