DNS Propagation Checker

Run live DNS checks from multiple countries and see where your new record is already visible on the map.

Add the new value after a DNS change so the map can show exactly where that value is visible. Leave blank to compare each region with the global consensus.

Run a propagation check to place live regional DNS results on the map.

Locations are live Globalping probes. DNS propagation is resolver-cache dependent, so nearby users can still see different results.

What does DNS propagation mean?

When a DNS record changes, recursive resolvers can keep the previous value until its cached TTL expires. During that window, users in different networks can receive different DNS answers.

ZoneCheckr uses distributed probes to sample DNS resolution from different countries. Enter an expected value when you know the new record you are waiting for; otherwise, the map compares each result with the most common answer in the measurement.
