DNS Record Lookup

Look up A, AAAA, MX, TXT, NS, CNAME and SOA records for a domain.

DNS Record Lookup checks a domain's A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records in real time. Quickly see which server a site points to, where its mail goes, and whether verification TXT records are in place.

Queries go to a trusted public resolver over DNS over HTTPS, and results are briefly cached for speed. Just enter a domain — no protocol or path needed.

Domaine.g. example.com (domain only, no protocol or path)

Record type

Record types at a glance

A / AAAA: the IPv4 / IPv6 address a domain points to
MX: mail servers (priority + host)
TXT: text values like SPF, DKIM, DMARC and ownership checks
NS: the nameservers delegated for the domain
CNAME: an alias to another domain
SOA: the zone's authority info (serial, refresh, etc.)
CAA: which certificate authorities may issue for the domain

What TTL means

Each record's TTL (seconds) is how long resolvers cache it. A long TTL slows propagation after a change. If you plan to change a record soon, lower its TTL in advance. To see whether a new value has spread worldwide, use the DNS Propagation Check; for IP-to-host lookups use Reverse DNS Lookup.

Frequently asked questions

I don't see the record I just changed.

DNS propagation takes time due to caching. Old values can persist for the previous TTL (often minutes to hours). This tool also caches results for 60 seconds.

Which resolver is used?

We query a public DNS resolver (e.g. Cloudflare) over DNS over HTTPS. Results can differ from asking the authoritative nameserver directly due to caching/propagation.

Can it look up internal domains?

No. Only public internet DNS is queried; internal-only zones aren't visible to external resolvers.

Does it do reverse (PTR) lookups?

This tool focuses on forward lookups. Reverse IP-to-host (PTR) lookups are available in the separate Reverse DNS Lookup tool.
