Free DNS Records Lookup (A, MX, TXT, CAA, DNSSEC)
Look up any domain's A, AAAA, MX, NS, TXT, CAA and SOA records and check DNSSEC, CAA and SPF posture. Free, read-only DNS tool by Neurobyte.
About this tool
DNS records reveal a lot about how a domain is configured — where its mail goes, which servers host it, and whether basic email and certificate protections are in place. This free DNS lookup queries any domain's A, AAAA, MX, NS, TXT, CAA and SOA records and checks its DNSSEC, CAA and SPF posture, giving you a quick, read-only picture of a domain's setup.
It's handy for troubleshooting mail delivery, verifying a migration, auditing your own domain's security records, or investigating an unfamiliar domain. The lookup is read-only and changes nothing — it simply reports what the public DNS says about the domain you enter.
Frequently asked questions
What DNS records does the tool look up?
A and AAAA (addresses), MX (mail servers), NS (nameservers), TXT (including SPF and verification records), CAA (which certificate authorities may issue), and SOA — plus a DNSSEC check.
What is DNSSEC and why does it matter?
DNSSEC cryptographically signs DNS records so resolvers can verify they weren't tampered with in transit, protecting against DNS spoofing and cache poisoning. The tool reports whether a domain has it enabled.
Is this lookup read-only?
Yes. It only queries and displays public DNS data for the domain you enter. It makes no changes to any domain or record.
