SharkDNS Live Query
Propagation
Query a DNS record from public resolvers around the world and compare answers.
No check yet
Enter a domain to query it from public resolvers across North America, Europe, and Asia.
How This Query Works
Propagation checks resolve the same record through independent public resolvers so you can see whether a recent change is visible everywhere.
Each resolver is queried in parallel over DNS-over-HTTPS and reports answers, TTL, and latency.
Different answers across regions usually mean caches still hold the old record; wait for the old TTL to expire.
Consistent answers everywhere mean the change has fully propagated.
