I am not an admin, but i might be able to provide some info. I have a good program to track I.P's. It does tell me it is from china, but almost every time i try to ping or connect to it, it gets timed out.

edit - It seems to me that someone probably faked there I.P address
It also tells me that the I.P is from a place called Guatemala, but the ISP is based in china or something
This is a list of possible I.P's maybe an admin can search these:

2: (70.87.254.29)

Hope that helps.
EDIT2 - It also tells me that the I.P could possibly be from Australia too
