What this tool does
DNS Lookup queries public DNS records such as A, AAAA, MX, TXT, CNAME, NS, SOA, and CAA for a domain.

🌍 DNS Lookup
Run a real DNS-over-HTTPS lookup for common record types. Results include TTLs, resolver status, and copyable CLI commands.
Network disclosure
- This lookup sends the domain name and selected DNS record type to a public DNS-over-HTTPS resolver.
- Use public domains only. Do not enter private internal hostnames or confidential infrastructure names.
How this lookup works
This uses Cloudflare DNS-over-HTTPS from your browser. It is useful for quick public DNS checks, but it may differ from your local resolver, private networks, or split-horizon DNS.
Why it is useful
It helps troubleshoot domain launches, email setup, ownership verification, SSL setup, and DNS propagation.
How it works
The tool sends a DNS-over-HTTPS request to a public resolver and displays answer records, status, TTLs, and raw JSON.
Best input
Enter a public domain name, not a private hostname or internal-only service.
Debugging tip
Compare results with dig, nslookup, and your DNS provider because resolvers can cache different answers during propagation.
Privacy note
This network tool sends the domain and record type to a public DNS-over-HTTPS resolver. Do not submit private internal hostnames or confidential infrastructure names.
Important limitation
Public DNS results may differ from local, corporate, VPN, or split-horizon DNS.
Quick answers
Why do I see old records?
DNS caches records until TTLs expire, so propagation can take time.
Can it check private DNS?
No. It checks public resolver data from the browser.
Common Use Cases
Verify DNS propagation
Check public A, AAAA, MX, TXT, CNAME, NS, SOA, and CAA records after changing DNS.
Debug email and domain setup
Inspect MX and TXT records for mail routing, SPF, DKIM, verification tokens, and ownership checks.
Copy CLI commands for deeper checks
Use the generated dig/nslookup commands when you need to compare browser DNS-over-HTTPS with your local resolver.
Network troubleshooting workflow
Pair subnet planning with DNS, headers, redirects, status codes, SSL checks, and webhook debugging.
