DNS Lookup
Resolve a domain’s A, AAAA, MX, NS, TXT and CNAME records in one place.
Reading your DNS records
DNS is the address book of the internet: it maps your domain to the servers that host your site and mail. When something looks wrong here — a missing MX, an unexpected A record, the wrong nameservers — it usually explains an outage or a delivery problem.
A / AAAA
The IPv4 / IPv6 addresses your domain points to.
MX
The mail servers that receive email for your domain.
NS
The nameservers authoritative for your zone.
TXT
Verification and policy records (SPF, DKIM, DMARC, ownership).
CNAME
Aliases that point one name at another.
DNSSEC
Signatures that let resolvers detect tampered answers. This lookup doesn’t validate them — use a dedicated DNSSEC validator.
