Allocates an Elastic IP address to your AWS account. After you allocate the Elastic IP address you can associate it with an instance or network interface. After you release an Elastic IP address, it is released to the IP address pool and can be allocated to a different AWS account.

[EC2-VPC] If you release an Elastic IP address, you might be able to recover it. You cannot recover an Elastic IP address that you released after it is allocated to another AWS account. You cannot recover an Elastic IP address for EC2-Classic. To attempt to recover an Elastic IP address that you released, specify it in this operation.

An Elastic IP address is for use either in the EC2-Classic platform or in a VPC. By default, you can allocate 5 Elastic IP addresses for EC2-Classic per region and 5 Elastic IP addresses for EC2-VPC per region.

For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to AllocateAddressAsync.
