GET THE SYSTEM BROWSER PRIVATE IP WHEN CLICK ON ANY LINK USING JAVASCRIPT

WHEN WE CLICK ON ANY LINK THEN HAVE TO GET THE MACHINE IP , WHICH CLICK IS CLIKED FROM WHICH IP ADDRESS OR WHICH MACHINE. (I mean, if i click on facebook with my system then we want to get my ip , at what time i have click on facebook from which machine or IP ).  FOR GETTING THE PARTICULAR MACHINE IP , WE CAN USE THIS FOR THAT . WE CAN EASILY FIND THE IP ADDRESS.
