Are DNS changes live worldwide?
Enter a domain to compare its record across several public resolvers at once and see the propagation status.
About this tool
When you change a DNS record, it must propagate to resolvers around the world, which can take up to 48 hours because of caching. This tool queries your record simultaneously from several trusted public resolvers (Google, Cloudflare, Quad9) to show whether they all agree or it's still propagating.
Frequently asked questions
What is DNS propagation?
The process of a DNS change taking effect across resolvers worldwide, delayed by caching.
Why are the results different?
The change hasn't fully propagated yet — some resolvers still have the old version cached.
How long does propagation take?
Depending on the TTL, usually a few minutes to 48 hours; a lower TTL is faster.
