An IPv6 is a conceptual term that refers to an IPv6 address and related properties. The IPv6 object is the API representation of an IPv6.
You can create and assign an IPv6 to any VNIC that is in an IPv6-enabled subnet in an IPv6-enabled VCN.
Note: IPv6 addressing is currently supported only in the Government Cloud.
For important details about IPv6 addressing in a VCN, see IPv6 Addresses.
