VPC Demo question

He gave a IPv4 cidr block range of 10.0.0./16 but then set the subnets as /24, would you know why? I thought the cidr need to be the same when setting up a VPC?

You can split your network to multiple networks by using subnetting. Example 10.0.0.0/16 is your VPC, and you can set 10.0.1.0/24 for Web servers, 10.0.2.0/24 for databases, 10.0.3.0/24 for application, and so on… This way it simplifies the management of your network, it adds more security, and reduces traffic
