/dns/propagation
DNS Propagation Checker
Check DNS propagation across 20 global resolvers in real-time.
Description
Monitor how DNS changes spread across the internet by querying 20+ public resolvers worldwide. See which resolvers have picked up your changes and which still serve stale records.
Essential after making DNS changes — switching hosting providers, updating nameservers, or modifying any DNS records. Instead of waiting and hoping, get instant visibility into propagation status across major resolvers like Google, Cloudflare, OpenDNS, and regional providers.
Use Cases
- Verify DNS changes have propagated globally after updating records
- Debug inconsistent website behavior across different regions
- Monitor TTL expiration and cache refresh across resolvers
- Validate DNS migration completeness before cutting over traffic
