Look up the A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records of a domain, with SPF and DMARC checks.
A DNS records checker queries a domain for its A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records and checks the email records SPF and DMARC. DNS decides where a domain's website and email are served.
This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.
Reads the real page at the moment you run it, with every redirect followed and shown.
Each finding says what it means and what to do next, not just a raw value.
Copy the output straight into your CMS, spreadsheet, ticket or client report.
Free, with no signup. Fair-use limits keep the tool fast for everyone.
Use a full public URL or domain.
The request is made from our server and nothing is stored.
Apply the fixes, then run it again.
Check the summary first: the web record, name servers, mail routing, SPF and DMARC. Then read the table for exact values and TTLs. After moving hosts, confirm the A record points to the new IP. For email deliverability, make sure there is exactly one SPF record and a DMARC record. If values look old, remember caching: a long TTL means resolvers may keep the old answer for hours. Compare with the registrar's DNS panel to confirm your changes saved.
The most common problem is two SPF records, which can make receivers reject both. Another is changing name servers without copying the old records first, which breaks email or subdomains. Do not set a very low TTL permanently, and do not forget www: it needs its own record or a redirect. Check after propagation, not immediately.
