DNS Propagation Checker

Compares results across major public DNS providers to check whether a change has propagated everywhere yet.

How to use this DNS propagation checker

  1. Enter a domain and record type.
  2. See what each major public DNS provider currently returns.
  3. If all providers agree, your change has fully propagated.

Why check multiple providers instead of one?

DNS changes don't apply everywhere instantly — each resolver caches records for the TTL duration set on that record. Comparing providers shows whether a recent change has fully rolled out, or whether some resolvers are still serving a cached, older value.

A note on what this tool is (and isn't)

This compares results across different DNS provider networks, not different geographic locations — it runs entirely from your browser, so it can't simulate querying from servers physically located in other countries. For true worldwide geographic propagation testing, a server-based tool is needed.

All providers show different results — is that a problem?

Right after a DNS change, this is completely normal — it just means propagation is still in progress. Give it time up to the old record's TTL value, then check again.

How long does full propagation usually take?

It depends entirely on the TTL (time-to-live) that was set on the record before the change — a record with a 24-hour TTL can take up to 24 hours for every resolver to pick up the new value.
