DNS Propagation Checker

Check if your DNS changes have propagated across major global DNS resolvers. Verify records from Google, Cloudflare, OpenDNS, and more.

What is DNS propagation?

DNS propagation is the time it takes for DNS changes to be updated across all DNS servers worldwide. When you update a DNS record, the change doesn't happen instantly everywhere — different DNS resolvers cache records for varying amounts of time based on the TTL (Time To Live) value.

Propagation typically takes anywhere from a few minutes to 48 hours, depending on the TTL values configured for your records and how aggressively each resolver caches DNS data.

This tool queries multiple major public DNS resolvers around the world to show you whether your DNS changes have been picked up by each one, helping you track the propagation progress in real time.
