 ## What does this repo do?
 - Creates an EKS Cluster with a VPC with Secondary CIDR block.
     - Secondary CIDR block is a VPC feature that allows you to add additional IP addresses to your VPC.
+    - We want to use the secondary CIDR block for the pods, and the default CIDR block of the VPC for the nodes.
+    - Thus defeating the IP Exhaustion problem.
 - Creates 3 Private subnets in the Secondary CIDR block with `/19` mask, so we can have available IP count of `3*8190` or `24570` for our pods.
 - Updates `aws-node` with Custom Networking configuration.
 - Creates ENIConfig for each of our subnets in the Secondary CIDR block.
