1. A method for domain name system (DNS) pre-caching comprising: receiving one or more uniform resource locator (URL) hostnames for DNS pre-fetch resolution prior to a user hostname request for any of the one or more URL hostnames; making a DNS lookup call for at least one of the one or more URL hostnames that are not cached by a DNS cache prior to the user hostname request; and discarding at least one IP address provided by a DNS resolver for the one or more URL hostnames, wherein a resolution result for at least one of the one or more URL hostnames is cached in the DNS cache in preparation for the user hostname request.
