Hi everyone. i know here many IT experts. i really need to know how to Trace real IP of any FB user even he is in chat with fb messenger and is it possible to trace the current location of the person?

What do you mean by tracing the exact location of that person? Or just tracking the city and country of that person and eventually the area of that person?
If you mean the exact location of that person, I would say it depends on that country.
In my country, when I turn off and turn on my modem, I see an ip outside of my country at sometime. (That's why tracking will be harder).
But Internet addresses (ip) will soon become more accurate and the user's guide will be available to everyone.
