What this global DNS lookup does
NetOpsKit sends the same bounded DNS query to healthy probes in different regions. Each probe uses its configured recursive resolver and returns structured records, TTL values, DNS status, and the resolver endpoint it contacted. Compare DNS answers across regions to see whether recent DNS changes are being observed consistently.
Understanding DNS answers
A and AAAA records map names to IP addresses. CNAME creates an alias, MX identifies mail exchangers, NS identifies authoritative name servers, TXT carries policies and verification data, and CAA restricts certificate authority issuance.
Why global answers can differ
Geo-aware DNS, CDN traffic steering, resolver caches, propagation delays, and different IPv4 or IPv6 policies can produce legitimate regional differences. Compare both the value and TTL before treating a difference as an error.
Common DNS statuses
NOERROR with no records means the name exists without the requested type. NXDOMAIN means the name does not exist. SERVFAIL indicates that the resolver could not complete validation or obtain a usable authoritative answer.
Frequently asked questions
Where are these DNS queries run?
Each query is executed by the NetOpsKit probe shown in the results. Comparing locations can reveal resolver cache, CDN, geolocation, or regional DNS differences.
Which DNS record types can I query?
The lookup supports A, AAAA, CNAME, MX, NS, TXT, and CAA records.
Why can locations return different answers?
Authoritative DNS services can use geolocation or traffic steering, while recursive resolvers can retain different cached answers until each record's TTL expires.
What does an empty NOERROR answer mean?
The domain exists, but the requested record type was not returned. This is different from NXDOMAIN, which means the queried name does not exist.
How long is a shared result available?
Distributed DNS results and their share link are retained in Redis for 14 days.
