Reporting an IP address

This morning while checking /var/log/secure to troubleshoot an issue with my Centos VPS, I found that there has been too many SSH bruteforce attempts from 54.93.174.60 for the past couple of days. I blocked the IP immediately and a quick google search on the IP 54.93.174.60 said there are quite a few who has complaints against this IP. Is there a common public place were I can report such IP addresses with proof where the ISPs check periodically and take the necessary if any of the IP addresses reported belong to them?

Is http://ift.tt/1q9h4C2 a respected project? I found this website while googling the mentioned IP address.
