IPv6 API Enhancement – IP Address CIDR Mask Support

Efficiently manage your IPv6 address ranges with our latest API update, featuring flexible network mask CIDR support. This enhancement empowers you to utilize custom CIDR masks, providing optimized address assignment and management for Virtual Network Interface Card (VNIC) configurations.

The introduction of the cidrPrefixLength attribute in the CreateIPv6 API allows for the allocation of contiguous IPv6 address blocks to VNICs, simplifying network management and representation. Custom mask values between 80 and 128 are supported, ensuring accurate network boundary definitions. For more information, see Assignment of IPv6 Addresses to a VNIC, Example of Enabling IPv6 in a VCN, Comparison of IPv4 and IPv6 for a VCN, and CreateIPv6 API.

Currently available through the API, this feature offers developers and automation experts a powerful tool for IPv6 address management. Stay tuned for upcoming releases as we continuously enhance our IP address management capabilities across the OCI platform.
