Issue
Is there any public info on what public IP address ranges Amazon EC2 uses? I would like to be able to lookup an IP and know whether or not it's an EC2 machine. I know that the DNS name given to EC2 machines gives a hint that it's an EC2 account, but I really prefer to just have an IP lookup available.

Amazon maintains the list of EC2 IP Ranges here: https://forums.aws.amazon.com/ann.jspa?annID=1701
