// Associates an Elastic IP address, or carrier IP address (for instances that are
// in subnets in Wavelength Zones) with an instance or a network interface. Before
// you can use an Elastic IP address, you must allocate it to your account. An
// Elastic IP address is for use in either the EC2-Classic platform or in a VPC.
// For more information, see Elastic IP Addresses
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html)
// 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. If you associate an Elastic IP address with an instance
// that has an existing Elastic IP address, the existing address is disassociated
// from the instance, but remains allocated to your account. [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. You cannot associate an Elastic IP address with
// an instance or network interface that has an existing Elastic IP address.
// [Subnets in Wavelength Zones] You can associate an IP address from the
// telecommunication carrier to the instance or network interface. You cannot
// associate an Elastic IP address with an interface in a different network border
// group. This is an idempotent operation. If you perform the operation more than
// once, Amazon EC2 doesn't return an error, and you may be charged for each time
// the Elastic IP address is remapped to the same instance. For more information,
// see the Elastic IP Addresses section of Amazon EC2 Pricing
// (http://aws.amazon.com/ec2/pricing/). We are retiring EC2-Classic on August 15,
// 2022. We recommend that you migrate from EC2-Classic to a VPC. For more
// information, see Migrate from EC2-Classic to a VPC
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-migrate.html) in the
// Amazon Elastic Compute Cloud User Guide.
