What is DNS Prefetch?
DNS Prefetch is a method to resolve the DNS of a specific domain. Sometimes, external links for images, JS, CSS, etc. are used on a website, which affects the loading time. DNS Prefetch can reduce the loading time of external links. In this tutorial, we will learn how to add DNS Prefetch to our Blogger site to speed it up. According to W3C, "The dns-prefetch link relation type is used to indicate an origin that will be used to fetch required resources, and that the user agent should resolve as early as possible."
