Global Visualization
15 strategic points make the DNS scan easy to understand on the map.
Visual DNS Propagation Test
Check real DNS answers through public DNS-over-HTTPS resolvers and visualize the scan on a modern global map.
Examples

15 Locations
0 successful
0 errors
DNS values come from real resolver queries. The cities on the map are visual points, not claimed physical DNS measurement stations.

Why DNS Propagation Matters
Resolvers can return different answers because of caching and TTL.
Real Resolvers
Cloudflare, Google and OpenDNS are queried through DNS-over-HTTPS.
Six Record Types
A, AAAA, CNAME, MX, TXT and NS are supported.
Export
Copy a text report or export the results as JSON.
No Storage
The Worker does not persist the DNS query.
Transparent Measurement
No invented IPs or random DNS values are used in normal production mode.
Frequently Asked Questions
What is DNS propagation?
DNS propagation is the time until DNS changes become visible on recursive resolvers.
Why can resolvers return different values?
Resolvers cache answers independently. TTL and cache state can therefore affect the result.
Does the map measure real cities?
No. The DNS answers are real, but one Worker cannot provide 15 independent geographic measurement stations. The map is therefore a visualization.
Which record types are supported?
A, AAAA, CNAME, MX, TXT and NS.
