AWS default VPC

Default VPCs are assigned a CIDR range of 172.31.0.0/16 and default subnets within a default VPC are assigned /20 netblocks within the VPC CIDR range. One default subnet is created for each Availability Zone in your default VPC.

Start VPC Wizard which includes four options:

• Amazon VPC with a single public subnet only
• Amazon VPC with public and private subnets
• Amazon VPC with public and private subnets and AWS Site-to-Site VPN access
