1. A method for domain name system (DNS) pre-caching comprising:

  • selecting one or more uniform resource locator (URL) hostnames for DNS pre-fetch resolution from one or more predicted hostnames based on detecting a user gesture for a predetermined period of time, wherein the selecting occurs prior to a user performing another user gesture;

    making a DNS lookup call for at least one of the one or more URL hostnames that are not cached by a DNS cache, wherein the making occurs in parallel with the selecting and prior to the another user gesture; and

    caching at least one IP address provided by a DNS resolver for the one or more URL hostnames in the DNS cache in preparation for a user hostname request based on the user gesture.
