The past couple of days I've been getting single or double page fetches from a Myspace IP:
63.135.84.X Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0)
All the other browser headers look legit. However, its sending a proxy header as well and the origin IP is a Bellsouth IP.
Anyone run into this? The IP range is 220.127.116.11 - 18.104.22.168 but all the visits come from the single 63.135.84.X IP.
