DNS Propagation Checker
Check whether a DNS record has propagated across multiple global resolvers in real time.
What is DNS propagation?
When you change a DNS record, the update has to spread from your authoritative nameservers to the recursive resolvers that the rest of the internet uses. “Propagation” is really about caching: old answers stick around until their TTL expires. This tool queries multiple independent public resolvers in parallel so you can see, at a glance, whether they all return the same answer yet.
Differences don’t always mean something is broken. Anycast, GeoDNS, and load-balancing can legitimately return different answers from different vantage points. Persistent disagreement is a sign the change hasn’t fully propagated — or that something is misconfigured.
Lookups are sent directly from your browser to each DNS-over-HTTPS resolver. StatusDrift never sees the queries.
