REAL SERVER-SIDE DIAGNOSTIC

DNS propagation checker

Compare public DNS records returned by Google and Cloudflare.

Record type

The domain is sent to two public DNS-over-HTTPS providers from this server. Anycast resolver regions are not verified; this is not a worldwide propagation map.

How this check works

Enter a public domain and choose a record type. The Internet Analysis server sends DNS-over-HTTPS queries to Google Public DNS and Cloudflare. Results show each provider’s status, returned records, TTLs, query duration and check time.

How to interpret the result

Matching status and records, excluding TTL differences, mean these two providers agree at the time checked. Different answers can reflect cache ages, geographic routing or load balancing. An error from either provider leaves the comparison incomplete.

Free public tool, no account required. Results describe the named server endpoint and moment, not every network or region.

Questions and limitations

Does this prove worldwide DNS propagation?

No. It compares two public recursive resolver providers from one server location. Anycast regions are not independently verified and other resolvers can retain older cached records.

Does it test the DNS resolver on my device?

No. Queries originate on the Internet Analysis server, not your device. Use client-side diagnostics to investigate your configured resolver.
