Enter a root domain or subdomain. DNS Look sends the query to a validating public resolver and organizes the response into a readable report.

What a DNS lookup tells you
The Domain Name System publishes records that connect a hostname to websites, mail systems, verification tokens, and other internet services. A lookup reads the records that are currently visible to recursive DNS resolvers.
A missing record does not always mean something is broken. For example, a domain that does not receive email may intentionally have no MX records. The useful question is whether the records match the service you expect the domain to provide.
Records included in this report
- A and AAAA — IPv4 and IPv6 addresses for a hostname.
- CNAME — an alias that points one hostname to another.
- MX — mail servers, ordered by the lowest preference number first.
- NS and SOA — the authoritative DNS service and zone metadata.
- TXT — text used for ownership checks and email authentication.
- CAA and SRV — certificate-authority policy and service discovery.
Quick answers
Frequently asked questions
Why can DNS results differ between tools?
Resolvers may have cached records at different times, and geographically distributed services can return different answers. Compare the TTL and try again after the old value has expired.
Does an all-record lookup use a DNS ANY query?
No. DNS Look requests each supported record type separately because authoritative servers are not required to return a complete zone in response to an ANY query.
Are these results authoritative?
The report shows the answer returned by a validating recursive resolver. For delegation problems, compare the result with the authoritative nameservers listed in the NS records.
