Oracleprovides the IPv6 prefix to use as the *same* CIDR for the `ipv6PublicCidrBlock`.When creating a subnet, specify the last 8 bits, 00 to FF.See [IPv6 Addresses](/iaas/Content/Network/Concepts/ipv6.htm).Example: `2001:0db8:0123::/56`                                                                                                                                                                        |

| ipv6_public_cidr_block   | core | string        | For an IPv6-enabled VCN, this is the IPv6 prefix for the VCN's public IP address space.The VCN size is always /56. This prefix is always provided by Oracle. If you don't provide acustom prefix for the `ipv6CidrBlock` when creating the VCN, Oracle assigns that value and alsouses it for `ipv6PublicCidrBlock`. Oracle uses addresses from this block for the `publicIpAddress`attribute of an [Ipv6](#/en/iaas/latest/Ipv6/) that has internet access allowed.Example: `2001:0db8:0123::/48`                                       |
