1. A method for domain name system (DNS) pre-caching comprising: detecting an entering activity in a URL address bar; gathering one or more uniform resource locator (URL) hostnames for DNS pre-fetch resolution from one or more predicted hostnames during the detection of the entering activity, wherein the gathering occurs substantially in parallel to the entering activity and occurs prior to a user entering a complete hostname for a user hostname request for any of the one or more URL hostnames and wherein the gathered one or more URL hostnames are duplicate free; 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 substantially in parallel to the gathering and entering activity and prior to the user hostname request; 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 the user hostname request.
