DNS Propagation Checker

How to use DNS Propagation Checker

Enter a DNS name and record type. Query two independent public resolver services from our server. Compare returned values while ignoring TTL and answer order. This does not use geographically distributed probes or prove global propagation; CDN or geographic DNS can legitimately differ.

Is this tool free?

You can complete three tools as a guest across this collection. Continue with Google for further use. Failed operations do not consume a successful use.

Where is my content processed?

Queries are sent from our server to Google Public DNS, Cloudflare, RDAP.org/registries, MACLookup or RIPEstat depending on the selected tool. Reports are cached for the duration stated in the workspace. Local/group MAC bit analysis does not send an external query. Usage analytics do not contain entered lookup values.

What does the result mean?

Results describe what the named providers reported at the shown time. Coverage, caching, redaction and resolver vantage points limit the conclusions. Review the tool-specific notes beside each result.

Can I use DNS Propagation Checker without signing up?

Yes. You can complete three successful operations across this tools collection as a guest. Continue with Google for further use. Failed operations do not reduce the successful-use allowance.

Does DNS Propagation Checker store my inputs in analytics?

Usage analytics record the tool, account or browser identity, status and time, without storing input text, passwords, tokens or file contents. Queries are sent to the named lookup providers. Short-lived reports are cached on our server: DNS 30 seconds, DNS comparison 15 seconds, RDAP 15 minutes, MAC assignments 24 hours and BGP 5 minutes. Inputs and results are not stored in usage analytics.
