> Make cassandra talk identify itself using the public ip (To avoid any future conflicts of private ips).
> 1) Split the logic of identification vs listen Address in the code.
> 2) Move the logic to assign IP address to the node into EndPointSnitch.
> 3) Make EC2 Snitch query for its public ip and use it for identification.
> 4) Make EC2 snitch to use InetAddress.getLocal to listen to the private ip.
