Global DNS Propagation Checker

Verify if your DNS changes have propagated across servers worldwide. Check A, AAAA, MX, CNAME, TXT, and other record types.

Understanding DNS Propagation

When you update DNS records, changes don't appear instantly worldwide. DNS servers cache records for the duration of their TTL (Time To Live). Until caches expire and refresh, some servers show old data while others show new.

Typical Propagation Times

Low TTL (300s): 5-30 minutes
Default TTL (3600s): 1-4 hours
High TTL (86400s): 24-48 hours

Tips for Faster Propagation

Lower your TTL before making changes, wait for old TTL to expire, make your changes, then restore normal TTL. This minimizes the window of inconsistency.
