-- | Creates a value of 'DescribeAddresses' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:
--
-- * 'daFilters' - One or more filters. Filter names and values are case-sensitive.     * @allocation-id@ - [EC2-VPC] The allocation ID for the address.     * @association-id@ - [EC2-VPC] The association ID for the address.     * @domain@ - Indicates whether the address is for use in EC2-Classic (@standard@ ) or in a VPC (@vpc@ ).     * @instance-id@ - The ID of the instance the address is associated with, if any.     * @network-interface-id@ - [EC2-VPC] The ID of the network interface that the address is associated with, if any.     * @network-interface-owner-id@ - The AWS account ID of the owner.     * @private-ip-address@ - [EC2-VPC] The private IP address associated with the Elastic IP address.     * @public-ip@ - The Elastic IP address.
--
-- * 'daPublicIPs' - [EC2-Classic] One or more Elastic IP addresses. Default: Describes all your Elastic IP addresses.
--
-- * 'daAllocationIds' - [EC2-VPC] One or more allocation IDs. Default: Describes all your Elastic IP addresses.
--
-- * 'daDryRun' - Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is @DryRunOperation@ . Otherwise, it is @UnauthorizedOperation@ .
