When you create a VPC in AWS, you assign it a CIDR block, which is a range of IP addresses. The number of available IP addresses depends on the size of the CIDR block.

For example, if you assign a CIDR block of /16 (which is the largest block you can assign to a VPC), you would have 65,536 IP addresses. However, AWS reserves the first four and the last one address in each subnet CIDR block, so the number of available addresses would be 65,531.

If you assign a smaller CIDR block, the number of available IP addresses would be less. For example, a /24 CIDR block would give you 256 IP addresses, but after AWS reserves the first four and the last one, you would have 251 available addresses.

So, the number of available IP addresses depends on the size of the CIDR block you assign to your VPC.
