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

Online tools:

• whatsmydns.net
• dnschecker.org
• Multiple geographic locations

Command line:

• `nslookup yourdomain.com`
• `dig yourdomain.com`
• Try accessing domain in browser

• 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
