Virtual Cloud Network (VCN) IP Enhancements
Introducing significant enhancements to Oracle Cloud Infrastructure Virtual Cloud Networks (VCN) that deliver greater flexibility, scalability, and simplified IP management:
IPv4 CIDR Addressing Support
- Flexible CIDR Mask Support: Use custom IPv4 CIDR masks to efficiently manage private IP space. This feature enables optimized address assignment and simplified management for Virtual Network Interface Card (VNIC) configurations.
- Comprehensive API and Console Support: IPv4 CIDR addressing is now fully supported through the Console, APIs, CLI, and SDKs.
- Dual IPv4 and IPv6 Support: Manage IPv4 and IPv6 addresses across your preferred interfaces for improved address management.
Expanded Service Limits for Greater Scalability
More IP Networks per VCN: Add up to 16 IPv4 CIDR blocks and 16 IPv6 prefixes to a single VCN to support growth and segmentation.
Enhanced Subnet Flexibility: Assign up to 16 IPv4 CIDR blocks and 16 IPv6 prefixes to each subnet for more granular control over network topology.
With these enhancements, you gain increased flexibility, simplified network management, and greater scalability for Oracle Cloud deployments. For more details, see:
