Changed a DNS record? See what public DNS resolvers return right now, and how long until the old value expires everywhere.
Pick the record you changed — A, AAAA, CNAME, MX, TXT or NS.
Optional: we’ll mark each resolver as updated or still old.
Resolvers showing the old value update once its TTL runs out; we show how long is left.
Usually minutes, at most the TTL the old record had (often 1–24 hours). Lower the TTL a day before a planned change to make it faster.
Your computer and browser also cache DNS. Try another network or flush your DNS cache — the resolvers here show what everyone else sees.
Not after the change — the old TTL has to run out. Next time, set a short TTL (300 s) before you change the record.
