What this tool helps with

DNS problems show up as indexing issues, email failures, or broken SSL/CDN setups.

  • OK at least one A/AAAA/CNAME and no lookup errors
  • Warning unusual setups (e.g., CNAME-only), missing common records
  • Error no A/AAAA/CNAME, resolver failures, record lookup errors

DNS Lookup Tool: verify core records fast

This tool fetches the most useful DNS records for a host: A, AAAA, CNAME, MX, NS, TXT, SOA, and CAA. It’s a quick way to confirm website + email DNS health.

Common use cases

  • Confirm where a domain points (A/AAAA/CNAME) after hosting/CDN changes.
  • Check email routing (MX) and SPF/DKIM/DMARC presence (TXT).
  • Verify certificate policy restrictions (CAA).
  • Spot delegation issues (NS/SOA) after a registrar move.

What to do if results look wrong

Double-check you’re querying the correct host, then confirm records inside your DNS provider. If you recently changed DNS, remember propagation can take time depending on TTL and caching resolvers.

FAQ

What does this DNS Lookup Tool show?

It fetches common DNS record types for a host: A, AAAA, CNAME, MX, NS, TXT, SOA, and CAA. Use it to quickly verify where a domain points and whether mail/security records exist.

Can I paste a full URL instead of a domain?

Yes. If you paste https://example.com/page the tool extracts example.com and looks up DNS for the host.

What’s the difference between A, AAAA, and CNAME?

A points to an IPv4 address, AAAA points to an IPv6 address, and CNAME makes a hostname an alias of another hostname (which then resolves to A/AAAA).

Why is “no A/AAAA/CNAME” flagged?

It usually means the host has no direct resolution for web traffic (no IPv4/IPv6 address and no alias). That can cause website downtime, crawl failures, and CDN/SSL issues.

What are MX and TXT records used for?

MX controls mail routing. TXT is often used for SPF/DKIM/DMARC (email authentication), plus domain verification tokens. TXT can be long — export CSV to review comfortably.

What do NS and SOA tell me?

NS shows which name servers are authoritative for the domain. SOA includes zone metadata like the primary server and serial number. These help debug delegation and DNS provider changes.

What is CAA and why can it matter?

CAA records can restrict which certificate authorities may issue SSL certificates for your domain. A wrong CAA policy can block certificate issuance or renewals.

Why do results sometimes look “wrong” right after DNS changes?

DNS changes may take time to propagate because resolvers cache answers based on TTL. If you recently updated records, wait and re-check later, or test using a different DNS resolver.
