How this test works
Globalping asks the resolver used by the selected remote probe for the requested record type.
REGIONAL DNS
Query DNS records from the resolver used by a selected remote probe.
Globalping asks the resolver used by the selected remote probe for the requested record type.
The answer reflects that resolver and location at measurement time. DNS caches and regional routing can produce different answers elsewhere.
It depends on the TTL of the old records: from minutes to 48 hours or more. Lower TTLs propagate faster. Mixed results for a while after a change are normal.
CAA tells certificate authorities which providers may issue TLS certificates for a domain. No CAA record is a valid result and normally means the domain has not restricted issuance through CAA.
It aliases one hostname to another, so www.example.com can point at example.com without duplicating address records. CNAMEs are also how most CDNs attach custom domains to their service.
Yes. DNS is public by design, and any resolver answers queries about any domain, which is how the tool on this page works. What you can't see is a domain's private configuration, like registrar or hosting logins.
Different resolvers have different caches and upstream paths. Regional routing, cache state and TTL all cause temporary differences, which is why comparing results from several regions beats trusting one answer.
DNS server not responding? Check A, MX and TXT records from several regions, then work through the fixes that solve most resolver failures.
