An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.
[EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.
[VPC in an EC2-Classic account] If you don't specify a private IP address, the Elastic IP address is associated with the primary IP address. If the Elastic IP address is already associated with a different instance or a network interface, you get an error unless you allow reassociation.
This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

The AssociateAddressRequest type exposes the following members
Gets and sets the property AllocationId.
[EC2-VPC] The allocation ID. This is required for EC2-VPC.
Gets and sets the property AllowReassociation.
[EC2-VPC] Allows an Elastic IP address that is already associated with an instance or network interface to be re-associated with the specified instance or network interface. Otherwise, the operation fails.
Gets and sets the property InstanceId.
The ID of the instance. This is required for EC2-Classic. For EC2-VPC, you can specify either the instance ID or the network interface ID, but not both. The operation fails if you specify an instance ID unless exactly one network interface is attached.
Gets and sets the property NetworkInterfaceId.
[EC2-VPC] The ID of the network interface. If the instance has more than one network interface, you must specify a network interface ID.
Gets and sets the property PrivateIpAddress.
[EC2-VPC] The primary or secondary private IP address to associate with the Elastic IP address. If no private IP address is specified, the Elastic IP address is associated with the primary private IP address.
