DNS Lookup Tool
Check DNS records (A, MX, TXT, etc.) for any domain name
Query the DNS records for any domain (A, AAAA, MX, TXT, CNAME, NS, and more) to see how it's configured. It's an everyday tool for diagnosing email delivery, verifying domain ownership records, checking propagation after a change, and confirming where a domain points.
How to use DNS Lookup Tool
- Enter the domain name you want to inspect.
- Choose the record type (or look up the common ones).
- Review the returned DNS records.
- Use the results to verify configuration or troubleshoot.
Frequently asked questions
What does each record type do?
A/AAAA map a domain to IP addresses, MX routes email, TXT holds verification and policy data like SPF/DKIM, CNAME aliases one name to another, and NS lists the authoritative nameservers.
Why don't I see my recent DNS change?
DNS records are cached based on their TTL, so changes can take minutes to hours to propagate. Lower the TTL before planned changes to speed this up.
How do I check email configuration?
Look at the MX records for mail routing and the TXT records for SPF, DKIM, and DMARC policies that affect deliverability and anti-spoofing.
