, WordPress,Webpage by resolving domain names through DNS Prefetch (rel=dns-prefetch) and Preconnect (rel=preconnect I've been researching the topic a bit lately and so far my (theoretical) conclusions are as follows: Browser support difference is negligible as of mid-2018, when counting the real global usage of browsers (~73% vs ~74%)dns-prefetch = DNS and preconnect = DNS + TCP + TLS. Note that DNS lookup is quite cheap to perform (a simple query-response to the DNS server, that is cached in the browser. Many people set their cookie path to /.

A web page provides a set of prefetching hints to the browser, and after the browser is finished loading the page, it begins silently prefetching specified documents and stores them in its cache dns-prefetch is basically a suggestion to the browser that it should consider prefetching that DNS lookup as soon as it's practical to do so. Therefore, it won't be a blocking action, and in general the browser (if doing things sanely) would not tie up the valuable bandwidth/connections pool during critical page load path with those extra DNS lookups, but would rather defer that. The other 2 other types of prefetching are DNS prefetching and prerendering.. DNS Prefetching. DNS prefetching lets you tell the browser to perform DNS lookups on a page in the background while the user is browsing. So by the time the user clicks a link as anticipated, the DNS look has already taken place, thus reducing latency
