What purpose would you have for wanting to know your 'contacts' IP address?
Also you show some grasp of the English language in your post so why not use it in the thread title? Addressing us as 'Oye' won't grant you any favours around here. (Especially as a first time poster.)
Also may I suggest
searching the forums and
searching the script database and
searching google before posting a thread such as this, not only will you most likely find the answers you want, but also learn valuable research skills and the knowledge to help others.
