rel=dns-prefetch

Baseline 2024
Newly available

Since June 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The dns-prefetch keyword for the rel attribute of the <link> element is a hint to browsers that the user is likely to need resources from the target resource's origin, and therefore the browser can likely improve the user experience by preemptively performing DNS resolution for that origin.

See Using dns-prefetch for more details.
