Now I will teach you How to find an Ip adress on Skype. So what you will need? Ofcourse Skype (you can download it Here: http://www.skype.com/intl/en-us/get-skype) and Comand Prompt (CDM), every computer has it (Start > All Programs > Accessories > Command Prompt). Now you needto downlad skype and add the victim wich IP you want to grab. Now, Double click the slave you wish to IP Grab.
Then open CMD. Go to Start > All Programs > Accessories > Right-click Command Prompt (CMD) & Run As Administrator. You must close other unwanted applications that are opened, such as other opened Skype friends. Leave open the slave you wish to IP Grab.In CMD (Command Prompt) Type " netstat -nbt " (without the quotes)A whole bunch of stuff should come up. You need to find Skype.exe. Now there will be more then one Skype.exe which is why you have to close the other unwanted tabs of Skype. Now there should notbe more than four IP's. All you have to do now is Track does 4, or even less, IP's and one will occur to be the one your looking for.
Hope it helped.
