DNS Lookup queries DNS record types — A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, and SRV — for any domain name. Use it to verify propagation after DNS changes, debug email delivery (MX/SPF/DKIM records), confirm domain ownership TXT records, and troubleshoot CDN routing. Queries run via the Cloudflare DNS-over-HTTPS API for accurate, uncached results.
How it Works
1Enter a domain name (e.g. example.com) in the input field.
2Select the record type to query from the dropdown.
3The tool queries Cloudflare's 1.1.1.1 DNS resolver over HTTPS.
4Results are displayed with record values, TTL, and type.
Frequently Asked Questions
Why does DNS Lookup show different results than my ISP's DNS?
DNS results depend on which resolver you query and whether the records are cached. Different resolvers (ISP, Google 8.8.8.8, Cloudflare 1.1.1.1) may show different results during propagation, as caches update at different times based on TTL. This tool queries Cloudflare's resolver for consistent, relatively fresh results.
How long does DNS propagation take after making changes?
Propagation depends on the record's TTL (Time To Live). Records with a 300-second (5 minute) TTL propagate within minutes globally. Records with a 86400-second (24 hour) TTL can take up to 24–48 hours to propagate fully as old cached values expire. Lowering the TTL before making a change reduces propagation time.
How do I verify an SPF record?
Query the TXT records for your domain. SPF records start with 'v=spf1'. If multiple SPF records are returned, that is a configuration error — only one SPF TXT record is allowed per domain. A valid SPF record defines authorised mail servers (IP ranges, include directives) and ends with -all (strict) or ~all (soft fail).
What is a PTR record?
A PTR (pointer) record maps an IP address back to a hostname — the reverse of an A record. PTR records are set in the reverse DNS zone (in-addr.arpa for IPv4) and are used by mail servers to verify that the sending server's IP has a valid hostname, reducing spam scores. Enter the IP address to look up its PTR record.
