comment mod_security block requests by http-host header
Try to dig a.tracker.thepiratebay.org from any DNS server in this list public-dns.tk/nameserver/cn.html and on each request there is a different answer. Same for tracker.thepiratebay.org which also appeared in our Host: headers. There is a post about it on viewdns.info/research/… with some additional sites. Trying to reverse some of the returned addresses using viewdns.info/reverseip shows that its pretty much random.

There is an extension for sharing trackers described here bittorrent.org/beps/bep_0028.html. But you are correct in that the 'Host:' header for all of these requests is a.tracker.thepiratebay.org or tracker.thepiratebay.org which might be or not be the actual target of these clients. It can also be fake clients just masking themselves as Chinese bittorents :)
