How to Check DNS Propagation

After changing DNS records, verify they've propagated globally.

Command Line

# Query specific DNS server\ndig @8.8.8.8 example.com\ndig @1.1.1.1 example.com\n\n# Query all record types\ndig example.com ANY\n\n# Check MX records\ndig example.com MX\n\n# Check TXT records\ndig example.com TXT

Online Tools

Use websites like dnschecker.org or whatsmydns.net to check propagation across multiple locations worldwide.

Speed Up Propagation

• Lower the TTL before making changes (e.g., to 300 seconds)
• Wait for the old TTL to expire before checking
• After propagation, increase TTL back for caching efficiency
