Tools / DNS lookup

DNS records lookup

Enter a domain or hostname to look up A and AAAA addresses, MX mail servers, NS, TXT, CAA and SOA records, plus reverse PTR and a DNSSEC indicator.

Record types returned

A / AAAA — IPv4 and IPv6 addresses, with reverse PTR where set.
MX — mail exchangers, sorted by priority.
NS — authoritative nameservers.
TXT — SPF, verification tokens, and anything else published at the apex.
CAA — which certificate authorities are allowed to issue (a missing CAA set is flagged).
SOA — primary NS, serial, refresh / retry / expire / minimum TTL.
DNSSEC — whether a DNSKEY is published for the zone.

To read the email records as a posture (SPF/DKIM/DMARC graded) use the SPF / DKIM / DMARC checker.
