DNS Prefetch

DNS Prefetch allows you to configure domain names for DNS prefetching, which can improve page load performance by resolving domain names before they are needed.

Setting​

DNS Prefetch List​

List of domain names to prefetch DNS for. This helps improve loading times for external resources.

ValuesDomain names, one per line (without http:// or https://)
DefaultNone

How It Works​

When DNS prefetch is enabled for a domain, the browser will perform DNS resolution for that domain in the background while the page is loading. This means when the browser needs to load resources from that domain, the DNS lookup has already been completed.

Common Use Cases​

  • External CDN domains
  • Analytics domains
  • Social media embeds
  • Third-party scripts
  • Keap API domains

Configuration​

Add domain names (without http:// or https://) to the prefetch list. For example:

  • cdn.example.com
  • fonts.googleapis.com
  • api.keap.com
