DNS Propagation Check
Validation Error
Global Resolvers
Query DNS propagation against top-tier global recursive DNS servers from different geographic locations.
Check propagation for A, AAAA, MX, CNAME, TXT, and NS records to ensure your DNS changes are fully distributed.
Watch resolution results populate progressively with concurrent client-side batches, delivering rapid feedback.
FAQS
What is DNS propagation?
DNS propagation is the timeframe it takes for DNS changes (like updating your IP address or MX records) to update across all servers on the internet globally.
How does the DNS Propagation Checker work?
It performs real-time DNS queries against 15+ public DNS servers around the world using direct UDP queries from the backend. The results show whether each server has updated to the new record.
What record types can I check?
You can check A (IPv4), AAAA (IPv6), MX (Mail server), CNAME (Canonical Name), TXT (Text), and NS (Name Server) records.
Why do some locations show old records?
DNS records are cached by resolvers according to their Time to Live (TTL). Some global servers might update immediately, while others wait for the TTL cache to expire.
