I have my website hosted on a dedicated IP. When I checked, other 3 unknown domains appear to be hosted on that IP and these are clones of my site.
My site is cleanbytes.net and the clones are zealusion.com, fringe-fx.info and fringe-fx.og
It seems to be sort of an attack, maybe I have many net "friends". Do you know what kind of DNS attack is this, the hosting company seems to be not guilty about this situation.
