Query DNS records
What this DNS lookup does
This tool asks a recursive DNS resolver for one record type at a time. It supports address, alias, mail, name server, text, and certification authority authorization records.
Understanding DNS answers
A and AAAA records map names to IP addresses. MX records identify mail servers, NS records identify authoritative name servers, CNAME records create aliases, TXT records carry text policies, and CAA records restrict certificate issuance.
Common issues
An empty answer is different from a nonexistent domain. DNS changes may also appear inconsistent until resolver caches expire according to record TTL values.
Frequently asked questions
Which DNS record types can I query?
The lookup supports A, AAAA, CNAME, MX, NS, TXT, and CAA records.
Why do I see an empty answer?
The domain can exist without publishing the selected record type. Try another relevant type.
Why do DNS results differ between resolvers?
Cached records can remain until their TTL expires, and split-horizon DNS may intentionally return different answers.
Does this test every DNS server worldwide?
No. This page queries the resolver configured for NetOpsKit. DNS propagation testing requires multiple regional resolvers.
