AWS VPC CIDR Overview || Session-2 ||

The IP addresses for your virtual private cloud (VPC) are represented using Classless Inter-Domain Routing (CIDR) notation. A VPC must have an associated IPv4 CIDR block. You can optionally associate additional IPv4 CIDR blocks and one or more IPv6 CIDR blocks. For more information, see IP addressing for your VPCs and subnets.
