Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) AssignPrivateIpAddresses API operation.

Syntax

Register-EC2PrivateIpAddress
-NetworkInterfaceId <String>
-SecondaryPrivateIpAddressCount <Int32>
-AllowReassignment <Boolean>
-PrivateIpAddress <String[]>
-Ipv4PrefixCount <Int32>
-Ipv4Prefix <String[]>
-Select <String>
-Force <SwitchParameter>
-ClientConfig <AmazonEC2Config>

Description

Assigns the specified secondary private IP addresses to the specified network interface. You can specify specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned from the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For more information about Elastic IP addresses, see Elastic IP Addresses in the Amazon EC2 User Guide. When you move a secondary private IP address to another network interface, any Elastic IP address that is associated with the IP address is also moved. Remapping an IP address is an asynchronous operation. When you move an IP address from one network interface to another, check network/interfaces/macs/mac/local-ipv4s in the instance metadata to confirm that the remapping is complete. You must specify either the IP addresses or the IP address count in the request. You can optionally use Prefix Delegation on the network interface. You must specify either the IPv4 Prefix Delegation prefixes, or the IPv4 Prefix Delegation count. For information, see Assigning prefixes to network interfaces in the Amazon EC2 User Guide.

Parameters

-AllowReassignment <Boolean>
Indicates whether to allow an IP address that is already assigned to another network interface or instance to be reassigned to the specified network interface.
Required?False
Position?3
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonEC2Config>
Amazon.PowerShell.Cmdlets.EC2.AmazonEC2ClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Ipv4Prefix <String[]>
One or more IPv4 prefixes assigned to the network interface. You can't use this option if you use the Ipv4PrefixCount option. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesIpv4Prefixes
-Ipv4PrefixCount <Int32>
The number of IPv4 prefixes that Amazon Web Services automatically assigns to the network interface. You can't use this option if you use the Ipv4 Prefixes option.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkInterfaceId <String>
The ID of the network interface.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-PrivateIpAddress <String[]>
The IP addresses to be assigned as a secondary private IP address to the network interface. You can't specify this parameter when also specifying a number of secondary IP addresses.If you don't specify an IP address, Amazon EC2 automatically selects an IP address within the subnet range. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?4
Accept pipeline input?True (ByPropertyName)
AliasesPrivateIpAddresses
-SecondaryPrivateIpAddressCount <Int32>
The number of secondary IP addresses to assign to the network interface. You can't specify this parameter when also specifying private IP addresses.
Required?False
Position?2
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'AssignedPrivateIpAddresses'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.AssignPrivateIpAddressesResponse). Specifying the name of a property of type Amazon.EC2.Model.AssignPrivateIpAddressesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
