A method for DNS pre-caching is provided. The method includes receiving uniform resource locator (URL) hostnames for DNS pre-fetch resolution prior to a user hostname request for any of the URL hostnames. The method also includes making a DNS lookup call for at least one of the URL hostnames that are not cached by a DNS cache prior to the user hostname request. The method further includes discarding at least one IP address provided by a DNS resolver for the URL hostnames, wherein a resolution result for at least one of the URL hostnames is cached in the DNS cache in preparation for the user hostname request. A system for DNS pre-caching is provided. The system includes a renderer, an asynchronous DNS pre-fetcher and a hostname table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Parallel, side-effect based DNS pre-caching","description":"Embodiments of the present invention include methods and systems for domain name system (DNS) pre-caching.
