A private IP is a conceptual term that refers to an IPv4 private IP address and related properties. The privateIp object is the API representation of a private IP.
Note: For information about IPv6 addresses, see Ipv6.
Each instance has a primary private IP that is automatically created and assigned to the primary VNIC during instance launch. If you add a secondary VNIC to the instance, it also automatically gets a primary private IP. You can't remove a primary private IP from its VNIC. The primary private IP is automatically deleted when the VNIC is terminated.
You can add secondary private IPs to a VNIC after it's created. For more information, see the privateIp operations and also IP Addresses.
Note: Only ListPrivateIps and GetPrivateIp work with primary private IPs. To create and update primary private IPs, you instead work with instance and VNIC operations. For example, a primary private IP's properties come from the values you specify in CreateVnicDetails when calling either LaunchInstance or AttachVnic. To update the hostname for a primary private IP, you use UpdateVnic.
To use any of the API operations, you must be authorized in an IAM policy. If you're not authorized, talk to an administrator. If you're an administrator who needs to write policies to give users access, see Getting Started with Policies.
Warning: Oracle recommends that you avoid using any confidential information when you supply string values using the API.
