What is DNS propagation?

After a DNS change, resolvers may continue serving older cached records until their TTL expires. “Propagation” describes the period when different caches can give different answers. The records are not pushed to every resolver at once.

How this worldwide DNS checker works

VVPN requests one Globalping probe in each of six continents. Each probe runs a DNS query from its own network. The results show the actual city, country, network, response and TTL. Availability varies; missing probes and failed queries are shown instead of being counted as success.

These are real geographic observations, but they are a sample. Matching answers do not prove that every cache worldwide has updated. CDNs, geographic routing, resolver policy and split DNS can also produce intentionally different results.

For a provider-to-provider comparison, use Compare resolvers. To investigate the source of a record, use a delegation trace.

A LITTLE CLARITY

Frequently asked questions

How long does DNS propagation take?

There is no universal waiting period. Existing TTLs, negative caching, delegation changes and resolver behavior all matter. Check the TTL of the old record and compare fresh observations over time.

Why are some regions unavailable?

A suitable probe may be offline, unable to reach a resolver, or unavailable under the provider’s current capacity and limits. The checker shows what actually returned and never invents a regional response.

Are my checks private?

Globalping measurements and submitted domains are public. Do not submit confidential names. See the tool data notice before running a check.
