|If you know which family member is hacking you, why do you need to trace the IP address? What do you think you are going to do with that information?|
Really, it's irrelevant. Whatever it may be, 64134178102 is not an IP address. Even if it were, you couldn't use it to trace the location of the device with that address.
If you have evidence that someone is misusing your computer in the way you describe, and you want to do something about it, then report it to the authorities. They know what they are doing. And keep your $5000 safe before someone inevitably cons you out of it.
