DNS Propagation Checker
Check a domain's DNS records across multiple global resolvers at once. Useful after making DNS changes to see which resolvers have picked up the new values.
Queries 12 resolvers globally via Cloudflare's DoH proxy. Results may vary by resolver cache state.
Frequently Asked Questions
How long does DNS propagation take?
It is bounded by the record’s previous TTL — resolvers serve the cached value until it expires. Most changes appear within minutes to a few hours; very high TTLs can take up to a day.
Why do different resolvers show different answers?
Each resolver caches independently and expires records at different times, so during a change some return the new value while others still serve the cached old one until their TTL lapses.
How do I make a future change propagate faster?
Lower the record’s TTL a day or two before the change so caches expire quickly, make the change, then raise the TTL back afterward.
