DNS Propagation Checker
Check DNS propagation for a domain across multiple global resolvers to see if your DNS changes have spread.
Frequently asked questions
How long does DNS propagation take?
DNS propagation typically takes 1–48 hours. The TTL on the old record determines how long caches hold the old value. A TTL of 3600s means resolvers may cache the old record for up to 1 hour after the change.
Why do different locations show different results?
Each DNS resolver checks its own cache. Until the TTL expires on each resolver worldwide, they return the cached (old) value. That's why propagation isn't instant.
