====== DNS Propagation =====

Understand how DNS changes spread across the internet.

> //DNS changes take time to propagate worldwide. Be patient when making changes.//

===== Overview =====

DNS propagation is the time it takes for DNS changes to spread across the internet. When you update an A record, it takes time for DNS servers worldwide to receive the update.

===== What is DNS Propagation =====

DNS propagation is the time it takes for DNS changes to spread across the internet. When you update an A record, it takes time for DNS servers worldwide to receive the update.

===== Propagation Time =====

  * **Typical**: 5 minutes to 48 hours
  * **Usually**: Within 1-2 hours
  * **TTL impact**: Lower TTL means faster propagation

===== Check Propagation =====

**Online tools:**
  * whatsmydns.net
  * dnschecker.org
  * Multiple geographic locations

**Command line:**
  * `nslookup yourdomain.com`
  * `dig yourdomain.com`
  * Try accessing domain in browser

===== Force Faster Propagation =====

  * Set low TTL before making changes
  * Clear local DNS cache: `ipconfig /flushdns` (Windows)
  * Use different DNS servers for testing
  * Wait at least 1 hour before troubleshooting

===== Troubleshooting =====

**Changes not appearing:**
  * Wait longer for propagation
  * Clear local DNS cache
  * Try different DNS servers
  * Verify correct record was added
