What is DNS Propagation?

DNS propagation is the time it takes for DNS record changes to spread across the internet. When you update your domain's DNS settings, each DNS server worldwide needs to update its cached version of your records.

Why Check Propagation?

  • After DNS Changes: Verify that your new records are visible globally after updating nameservers, A records, or MX records.
  • Troubleshooting: Identify if DNS issues are localized or worldwide. Use DNS Lookup for detailed record inspection.
  • Migration Verification: Confirm that a website or email migration is properly propagated before decommissioning old servers.

Propagation Time

DNS propagation typically takes 15 minutes to 48 hours, depending on TTL (Time To Live) values and how aggressively DNS servers cache records. Lower TTL values before making changes can speed up propagation.

Related Questions

How long does DNS propagation take?
Most DNS changes propagate within 15-30 minutes for servers with low TTL values. Full global propagation can take up to 48 hours for servers that cache aggressively.
What's the difference between DNS Propagation and DNS Lookup?
DNS Propagation checks if your records are visible across multiple global servers. DNS Lookup queries a single server for detailed record information.
