[How To] Remove DNS-Prefetch WordPress
What is DNS-Prefetch ?
DNS prefetching is an attempt to resolve domain names before a user tries to follow a link. This is done using the computer’s normal DNS resolution mechanism.
The main reason for rel=dns-prefetch to exist is to speed up the way web pages load when they are using different domains for page resources. This process is often called “DNS prefetching“.
The WordPress link looks like this:
<link rel='dns-prefetch' href='//s.w.org' />
