Free agency tools / DNS Propagation Checker
Has your DNS change propagated?
After you edit a record it takes time for resolvers to catch up. This asks several major public resolvers for the same record and shows whether they agree yet — the practical signal that a change has landed.
How it works
- 1Enter a domain and pick a record type.
- 2We query several major public resolvers (Cloudflare, Google, AdGuard, NextDNS) for the same record.
- 3If they all agree, the change has taken hold; if they differ, it's still propagating.
Frequently asked
What does propagation actually mean?
Resolvers cache DNS for a record's TTL. 'Propagated' means the caches have expired and everyone now sees the new value.
Why do resolvers disagree for my site?
Either the change is still spreading, or the record is round-robin (returns different IPs by design), which always looks inconsistent.
How long does propagation take?
Usually minutes to a few hours, bounded by the record's previous TTL. Lower the TTL before a planned change.
