DNS Propagation
DNS Propagation Checker
Enter a domain. We query it against 45 public DNS resolvers around the world — across every continent — and plot each answer on a map. If they disagree, your DNS change is still propagating. After a cutover, watch them converge on the new record.

What this checks
- Worldwide resolvers: 45 public resolvers across every continent, on a map.
- Consistency: agreement means propagated; disagreement means still in flight.
- Any record type: A, AAAA, CNAME, MX, TXT, NS.
- Note: big sites use geo/anycast DNS, so differing answers can be by design, not lag.
Frequently asked questions
How long does DNS propagation take?
Usually minutes to a few hours with a low TTL, but up to 24–48 hours worldwide. Lower the record's TTL before you change it to speed this up.
Why do resolvers return different IPs?
Either the change is still propagating, or the domain uses geo/anycast DNS that returns different answers by region on purpose.
Which resolvers do you query?
45 public resolvers across every continent — Cloudflare, Google, Quad9, OpenDNS, Yandex, Baidu and more — queried directly and compared.
