My PA app connects to a database hosted at Amazon's RDS. I am trying to add security to the database by restricting inbound IP addresses, using EC2 VPS Security Groups (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html#vpc-security-groups)
I need to supply the Source IP, in CIDR notation. What should I set it to, so that all my PyAnywhere apps can access (read/write) the database?
