Check the DNS records of a domain on public DNS servers around the world.
The DNS propagation checker asks about 20 public DNS servers in different countries – Google, Cloudflare, Quad9, OpenDNS, Yandex, AliDNS and more – for the records of a domain, all at once. See which servers already return your new values and which still have the old ones.
After you change DNS records, resolvers keep the old answer until its TTL expires. Add the expected value to mark the servers that are up to date in green.
In the USA, Europe, Russia, China, Korea and Taiwan.
A, AAAA, CNAME, MX, NS and TXT.
Highlights the servers that return it.
How fast each server answered.
Usually minutes to a few hours, up to 48 hours depending on the TTL of the old record.
Each resolver caches records for their TTL, and some websites use geo DNS that answers differently by location.
Lower the TTL of the record a day before the change; afterwards you can raise it again.
