Understanding DNS Propagation

What is DNS Propagation?

DNS propagation is the time it takes for DNS changes to spread across all DNS servers worldwide. When you make changes to your domain's DNS records (such as changing your website's IP address), these changes don't take effect immediately everywhere.

Due to DNS caching at various levels, it can take anywhere from a few minutes to 48 hours for changes to fully propagate. During this time, some users might see your old DNS records while others see the new ones.

Factors Affecting Propagation Speed

Several factors influence how quickly DNS changes propagate:

  • TTL (Time To Live): The cache duration set on your DNS records. Lower TTL values result in faster propagation.
  • DNS Provider: Some DNS providers update their servers more frequently than others.
  • ISP Caching: Internet Service Providers may cache DNS records independently of TTL values.
  • Browser Cache: Web browsers also maintain their own DNS cache.
  • Geographic Location: Some regions may receive updates faster than others.

Best Practices for DNS Changes

Follow these recommendations for smoother DNS transitions:

  • Lower your TTL values to 300-600 seconds at least 24-48 hours before making significant DNS changes.
  • Schedule DNS changes during low-traffic periods for your website.
  • Use a propagation checker (like this one) to monitor the progress of your changes.
  • Be patient and allow sufficient time for full propagation before considering your change complete.
  • After changes have fully propagated, you can increase TTL values again for better performance.
