Same subnet trying to rip stream

[soulful1]

For a few weeks now, I've been finding computers from the same subnet trying to rip my stream. One by one I would ban the stream, but they would just go to another machine and try again. Anyone know anything about the following ip's or subnet?? 212.239.160.178 , 212.239.200.91 , 212.239.160.94 , 212.239.160.179 , 212.239.188.253 just to name few.

Thanks!
