Amazon Virtual Private Cloud (VPC) now allows you to resize your VPC prefix list, making it easier to manage your security posture and routing behavior as your network grows. Prefix lists allow you to group multiple CIDR blocks into a single object, and use it as a reference to simplify network configuration. You can share your prefix list with other AWS accounts using Resource Access Manager (RAM) and use it to configure VPC routes tables, security groups, and AWS Transit Gateway (TGW) route tables.
