The private IP's availability domain. This attribute will be null if this is a secondary private IP assigned to a VNIC that is in a regional subnet.
Example: {@code Uocm:PHX-AD-1}
The OCID of the compartment containing the private IP.
Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags.
Example: {@code {\"Operations\": {\"CostCenter\": \"42\"}}}
A user-friendly name. Does not have to be unique, and it's changeable. Avoid entering confidential information.
Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags.
Example: {@code {\"Department\": \"Finance\"}}
The hostname for the private IP. Used for DNS. The value is the hostname portion of the private IP's fully qualified domain name (FQDN) (for example, {@code bminstance1} in FQDN {@code bminstance1.subnet123.vcn1.oraclevcn.com}). Must be unique across all VNICs in the subnet and comply with RFC 952 and RFC 1123.
For more information, see [DNS in Your Virtual Cloud Network](https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/dns.htm).
Example: {@code bminstance1}
The private IP's Oracle ID (OCID).
The private IP address of the {@code privateIp} object. The address is within the CIDR of the VNIC's subnet.
However, if the {@code PrivateIp} object is being used with a VLAN as part of the Oracle Cloud VMware Solution, the address is from the range specified by the {@code cidrBlock} attribute for the VLAN. See Vlan.
Example: {@code 10.0.3.3}
Whether this private IP is the primary one on the VNIC. Primary private IPs are unassigned and deleted automatically when the VNIC is terminated.
Example: {@code true}
The OCID of the subnet the VNIC is in.
However, if the {@code PrivateIp} object is being used with a VLAN as part of the Oracle Cloud VMware Solution, the {@code subnetId} is null.
The date and time the private IP was created, in the format defined by RFC3339.
Example: {@code 2016-08-25T21:10:29.600Z}
The OCID of the VNIC the private IP is assigned to. The VNIC and private IP must be in the same subnet. However, if the {@code PrivateIp} object is being used with a VLAN as part of the Oracle Cloud VMware Solution, the {@code vnicId} is null.
A private IP is a conceptual term that refers to an IPv4 private IP address and related properties. The {@code 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 {@code privateIp} operations and also [IP Addresses](https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingIPaddresses.htm).
*Note:** Only {@link #listPrivateIps(ListPrivateIpsRequest) listPrivateIps} and {@link #getPrivateIp(GetPrivateIpRequest) 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 {@link #launchInstance(LaunchInstanceRequest) launchInstance} or {@link #attachVnic(AttachVnicRequest) attachVnic}. To update the hostname for a primary private IP, you use {@link #updateVnic(UpdateVnicRequest) updateVnic}.
{@code PrivateIp} objects that are created for use with the Oracle Cloud VMware Solution are assigned to a VLAN and not a VNIC in a subnet. See the descriptions of the relevant attributes in the {@code PrivateIp} object. Also see Vlan.
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](https://docs.cloud.oracle.com/iaas/Content/Identity/Concepts/policygetstarted.htm).
