Allocates an Elastic IP address to your Amazon Web Services 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 Amazon Web Services account.
You can allocate an Elastic IP address from an address pool owned by Amazon Web Services or from an address pool created from a public IPv4 address range that you have brought to Amazon Web Services for use with your Amazon Web Services resources using bring your own IP addresses (BYOIP). For more information, see Bring Your Own IP Addresses (BYOIP) in the Amazon Elastic Compute Cloud User Guide .
[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 Amazon Web Services 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 .
You can allocate a carrier IP address which is a public IP address from a telecommunication carrier, to a network interface which resides in a subnet in a Wavelength Zone (for example an EC2 instance).
Note
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 in the Amazon Elastic Compute Cloud User Guide .

--domain
(string)
Indicates whether the Elastic IP address is for use with instances in a VPC or instances in EC2-Classic.
Default: If the Region supports EC2-Classic, the default is
standard
. Otherwise, the default isvpc
.Possible values:
vpc
standard
--address
(string)
[EC2-VPC] The Elastic IP address to recover or an IPv4 address from an address pool.
--public-ipv4-pool
(string)
The ID of an address pool that you own. Use this parameter to let Amazon EC2 select an address from the address pool. To specify a specific address from the address pool, use the
Address
parameter instead.
--network-border-group
(string)
A unique set of Availability Zones, Local Zones, or Wavelength Zones from which Amazon Web Services advertises IP addresses. Use this parameter to limit the IP address to this location. IP addresses cannot move between network border groups.
Use DescribeAvailabilityZones to view the network border groups.
You cannot use a network border group with EC2 Classic. If you attempt this operation on EC2 Classic, you receive an
InvalidParameterCombination
error.
--customer-owned-ipv4-pool
(string)
The ID of a customer-owned address pool. Use this parameter to let Amazon EC2 select an address from the address pool. Alternatively, specify a specific address from the address pool.
--dry-run
| --no-dry-run
(boolean)
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 isUnauthorizedOperation
.
--tag-specifications
(list)
The tags to assign to the Elastic IP address.
(structure)
The tags to apply to a resource when the resource is being created.
Note
The
Valid Values
lists all the resource types that can be tagged. However, the action you’re using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you’re using, you’ll get an error.ResourceType -> (string)
The type of resource to tag on creation.
Tags -> (list)
The tags to apply to the resource.
(structure)
Describes a tag.
Key -> (string)
The key of the tag.
Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with
aws:
.Value -> (string)
The value of the tag.
Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
See ‘aws help’ for descriptions of global parameters.
Note
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
Example 1: To allocate an Elastic IP address from Amazon’s address pool
The following allocate-address
example allocates an Elastic IP address. Amazon EC2 selects the address from Amazon’s address pool.
aws ec2 allocate-address
Output:
{
"PublicIp": "70.224.234.241",
"AllocationId": "eipalloc-01435ba59eEXAMPLE",
"PublicIpv4Pool": "amazon",
"NetworkBorderGroup": "us-west-2",
"Domain": "vpc"
}
For more information, see Elastic IP addresses in the Amazon EC2 User Guide.
Example 2: To allocate an Elastic IP address and associate it with a network border group
The following allocate-address
example allocates an Elastic IP address and associates it with the specified network border group.
aws ec2 allocate-address \
--network-border-group us-west-2-lax-1
Output:
{
