rel=dns-prefetch #
::: section-content
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.
