What this check shows
A global DNS lookup compares how independent recursive resolvers answer the same DNS question. This helps separate a local cache problem from a wider DNS, delegation or provider issue.
DNSRadar queries global resolvers in parallel and reports the returned value, status and latency so you can confirm whether a record is consistent worldwide.
When to use it
- Checking any DNS record after a change
- Comparing local DNS with public resolvers
- Finding stale cached answers
- Collecting evidence for hosting or DNS support
How to read the result
- Matching answers across providers normally indicate the record is globally stable.
- Different answers can be valid for CDNs, but unexpected differences after a migration usually point to caching or authoritative inconsistency.
- Consistent NXDOMAIN, SERVFAIL or timeout states should be investigated at the authoritative DNS and delegation level.
Questions
Which DNS record types can I check?
DNSRadar supports A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV and CAA lookups from the same global checker.
Why use a global DNS lookup instead of my computer?
Your computer usually queries one resolver. A global lookup shows whether other networks already see the same DNS answer.
