DNS propagation refers to the time it takes for DNS changes to spread across the internet's DNS servers. When you update DNS records, the changes don't happen instantly everywhere.

This tool checks your domain's DNS records across 25+ globally distributed public DNS servers to verify propagation status. It provides detailed information about each server including:

• Server location and provider information
• Response time for each query
• Complete DNS answers with TTL values
• CNAME chain resolution showing all intermediate steps
• IPv4 (A) and IPv6 (AAAA) record resolution

A domain is considered "propagated" when at least 80% of the servers return successful responses. Consistency indicates that all servers are returning the same DNS answers.
