hn.kd.ny.adsl: Research, Ban
This guy hn.kd.ny.adsl seems innocent enough, until I tried to look him up, only to find no positive IP address. Others have posted that they, too, cannot find his IP address in order to ban him. Hmmm, let me track him down.
This hacker is prolific in that he rarely repeats the third octet, making it harder to ban by a narrower range. You’ll need to go up to the second octet to cover his IP ranges. He uses predominantly China Unicom Henan. Only once did he go to China Unicon Fujian, which might just be an outlier data point.
