I agree, this looks to be bit torrent traffic, The Pirate Bay has a practice of injecting fake client IP address. I have a feeling that is what your seeing. I would write more but power is out and the battery is going....

Note the  "64 31 3a 61 64 32 3a 69 64 32 30 3a"
and also the  textual reference to  info_hash

I'm seeing thousands of these per minute at one location, hundreds of unique

Thanks much
