ISP Targeting

You can target a specific ISP by adding the parameter  country-US-isp-comcast (replace with a country code and ISP to your desire) when authenticating.

Example: username-country-US-isp-comcast

Example:   
curl -x premium.residential.proxyrack.net:10000 -U username-country-US-isp-comcast http://example.com

When targeting an ISP make sure you do not include any spaces and we wildcard match the result to right comast* (comcas matches comcast, comca matches comcast, etc)
