A VPC spans all of the Availability Zones in a Region. After you create a VPC, you can add one or more subnets in each Availability Zone. For more information, see Subnets for your VPC.
VPC IP address range
When you create a VPC, you specify its IP addresses as follows:
-
IPv4 only – The VPC has an IPv4 CIDR block but does not have an IPv6 CIDR block.
-
Dual stack – The VPC has both an IPv4 CIDR block and an IPv6 CIDR block.
For more information, see IP addressing for your VPCs and subnets.
