DNS Propagation Checker
Changed your DNS? Check whether the new records are live on major public DNS resolvers around the world.
Large resolvers use anycast, so results reflect their nearest data centre to our server. Differences usually mean old records are still cached (see TTL).
Our server asks each public DNS resolver for the record. Nothing is stored.

Back to the toolWhat is DNS propagation?
The time it takes for DNS changes to reach DNS servers worldwide. Old records stay cached until their TTL expires.
How long does propagation take?
Usually minutes to a few hours, up to 48 hours for nameserver changes.
Why do servers show different results?
Some still have the old record cached. Wait for the TTL to expire.
Can I speed it up?
Lower the TTL (e.g. 300 seconds) a day before making changes.
