Understanding DNS Propagation

When you update your DNS records (like changing hosting providers or adding a verification TXT record), the changes don't happen instantly. They must "propagate" across the internet's network of DNS servers.

Why does it take time?

Each DNS server (ISP, Google, Cloudflare) caches your records for a specific time, defined by the TTL (Time To Live). Until this timer expires, they will serve the old records.

What this tool does

We query multiple DNS resolvers located in different geographic regions (US, Europe, Asia, South America) to show you exactly which parts of the world see your new records and which are still seeing the old ones.
