What is CIDR in Oracle Cloud?
We’re excited to announce the immediate availability of the modifiable virtual cloud network (VCN), Subnet, and VLAN classless inter-domain routing (CIDR) feature in Oracle Cloud Infrastructure (OCI). This feature allows you to dynamically change the size of your VCN by adding or resizing existing CIDR ranges.
