Check whether a DNS record change has propagated by querying multiple public resolvers around the world and comparing their answers side by side.

🎓Learn: DNS propagation
Why do changes take time to appear?▾
Resolvers cache each record for its TTL. Until that timer expires they keep serving the old answer, so a change rolls out gradually as caches around the world expire at different moments — not all at once.
How can I make changes propagate faster?▾
Lower the record’s TTL (e.g. to 300s) a day before the change, so caches hold the old value for less time. Raise it again afterwards for efficiency. You can’t force third-party caches to flush early.
What does “consistent everywhere” mean here?▾
We compare the answers from several independent public resolvers. If they all match, the change has almost certainly finished propagating for typical users. If they differ, some caches are still serving the previous record.
