Check if your DNS changes have propagated worldwide across 20 global resolvers
DNS propagation is the process of DNS changes spreading across all resolvers worldwide. After updating your DNS records, it can take from a few minutes to 48 hours for all servers to reflect the change, depending on the TTL of the previous record.
This tool queries 20 DNS servers across USA, Russia, Germany, Europe, China, and Asia to show you exactly where your new DNS records have propagated. If you see inconsistent results across servers, it means propagation is still in progress.
Common use cases: verifying A record update after server migration, checking NS delegation after domain transfer, confirming MX record changes for email migration, and validating TXT records for SPF/DKIM/DMARC setup. After checking propagation, use our DNS Lookup tool for detailed record inspection.
DNS Propagation is the process of updated DNS records spreading across all servers worldwide. Takes from minutes to 48 hours.
Due to TTL (Time To Live) — cache on DNS servers. Higher TTL means longer propagation. Lower TTL before making changes.
