Global DNS Propagation Checker

Queries a record across a dozen independent public resolvers, spread across US and European providers, and shows whether they all agree yet. If they don't, the record is either still propagating or is configured differently at different providers.

How to use this tool

1. Enter the domain (or full record name) and pick a record type, then click Check.
2. Compare results across the listed resolvers — full agreement means the record has finished propagating everywhere checked.
3. A split result usually just means propagation is still in progress; give it the record's TTL in seconds and check again.
4. A split that never resolves itself points to different answers configured at different providers, not propagation delay.

Use it right after changing a DNS record to see how far the change has actually spread, instead of guessing from a single lookup on your own machine, which only reflects whatever resolver and cache your ISP happens to use.
