# DNS Propagation Checker

Ask the same question of ten large public DNS resolvers run by different operators and see their answers side by side, so you can tell which ones have picked up your change and which still serve a cached value. These resolvers are anycast networks: each answer comes from the operator's node nearest to our server.

- **Limits** No file upload · Up to 666 runs a day
- **Where it runs** Runs on our server; no file is uploaded.
- **Cost** Free, with the limits above. No account needed.

**What it's for:** Check whether a DNS change has propagated by asking ten public resolvers (Google, Cloudflare, Quad9, OpenDNS and more) and comparing their answers. Instant.

**What trips people up:** **Why do some resolvers still show the old IP?** Those resolvers cached the previous answer and will keep serving it until that cache entry expires.
