For Amazon, a Dedicated network option is available using the Tenancy option.

For Amazon, please refer http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html for Linux, and http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/using-network-security.html for Windows instances.
A single CIDR block can be assigned to a Network, and helps create single or multiple subnets.

For Amazon, please refer http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Subnets.html
Tenancy value determines whether the underlying hardware is shared or dedicated for our use by the cloud provider.
