DNS Propagation Checker — Global DNS Test

Global DNS propagation — resolver status and TTL

How to Use This Tool

  1. Enter hostname and record type.
  2. Twelve resolver networks are queried.
  3. Green means the answer matches; red means mismatch or timeout.

About This Tool

After you change DNS at a registrar, not every resolver updates instantly. This tool queries multiple public DNS networks and shows whether each location returns your expected answer.

Common use cases

  • •Confirm global resolvers see new DNS after migration
  • •Debug why some users still hit old servers

How long does propagation take?

Often minutes to a few hours. Old TTL values can delay updates up to 24–48 hours in edge cases.

Why resolvers disagree

Caching, geographic anycast, and stale TTL on parent zones can make some locations show old data while others show new.
