Look up DNS records for any domain or IP address. Choose a record type, or ANY to fetch the common record set at once. Use PTR with an IP address for a reverse-DNS lookup.
About DNS records
The Domain Name System (DNS) maps human-readable domain names to the records that make the internet work. This tool queries the public DNS in real time and shows you exactly what resolvers see.
Common record types
A / AAAA — the IPv4 / IPv6 address a name points to.
MX — mail servers that accept email for the domain (lower priority = preferred).
TXT — free-form text, used for SPF, DKIM, DMARC and domain verification.
NS — the authoritative nameservers for the domain.
CNAME — an alias pointing one name at another.
SOA — the zone's start-of-authority record and serial number.
CAA — which certificate authorities may issue certificates for the domain.
PTR — reverse DNS: the hostname an IP address resolves back to.
