-- | Assigns one or more secondary private IP addresses to the specified network
-- interface. You can specify one or more specific secondary IP addresses, or
-- you can specify the number of secondary IP addresses to be automatically
-- assigned within the subnet's CIDR block range. The number of secondary IP
-- addresses that you can assign to an instance varies by instance type. For
-- information about instance types, see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html Instance Types> in the /Amazon ElasticCompute Cloud User Guide for Linux/. For more information about Elastic IP
-- addresses, see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html Elastic IP Addresses> in the /Amazon Elastic Compute Cloud UserGuide for Linux/.
