Global DNS

Global DNS propagation check.

Check resolvers across the Americas, Europe, Africa, Asia and Oceania with automatic diagnostics and exportable results.

Resolver coverage

23 configured public resolvers

Coverage view

19 approximate locations

4 anycast endpoints

Locations are approximate metadata, not live probe origins. Anycast resolvers may answer from a different region.

DNS tools

Start with the record you need to verify.

DNSRadar is built for developers, sysadmins and technical site owners checking migrations, mail records, CDN changes and resolver differences.

How DNSRadar checks propagation

DNSRadar sends the selected lookup to independent public resolvers across the Americas, Europe, Africa, Asia and Oceania. Every resolver is queried in parallel and reported with its answer, status, resolver IP and measured latency.

Comparing those responses helps distinguish a local cache issue from partial global propagation, stale DNS answers or inconsistent authoritative DNS configuration.

What result statuses mean

OK: The resolver returned one or more records.
No answer: The DNS name exists, but no record of the requested type was returned.
NXDOMAIN: The queried DNS name was reported as missing.
SERVFAIL: The resolver could not complete the lookup, often because of delegation or DNSSEC issues.
Timeout: The resolver did not answer within the configured limit.

Practical DNS checks

Use DNSRadar when one network sees a change and another does not.

DNS issues often look random because users depend on different recursive resolvers, cache ages and network paths. A global comparison gives you a clearer pattern before opening a support ticket or rolling back a migration.

Website migration

Compare A, AAAA and CNAME answers before shutting down the old server.

Email migration

Verify MX, TXT, SPF, DKIM and DMARC records after changing providers.

DNSSEC or delegation failure

Look for SERVFAIL patterns across validating public resolvers.

Certificate renewal

Check CAA records before requesting or renewing TLS certificates.
