assign-ipv6-addresses¶

Description¶

Assigns one or more IPv6 addresses to the specified network interface. You can specify one or more specific IPv6 addresses, or you can specify the number of IPv6 addresses to be automatically assigned from within the subnet’s IPv6 CIDR block range. You can assign as many IPv6 addresses to a network interface as you can assign private IPv4 addresses, and the limit varies per instance type. For information, see IP Addresses Per Network Interface Per Instance Type in the Amazon Elastic Compute Cloud User Guide .

You must specify either the IPv6 addresses or the IPv6 address count in the request.

Synopsis¶

  assign-ipv6-addresses
[--ipv6-address-count <value>]
[--ipv6-addresses <value>]
--network-interface-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--ipv6-address-count (integer)

The number of additional IPv6 addresses to assign to the network interface. The specified number of IPv6 addresses are assigned in addition to the existing IPv6 addresses that are already assigned to the network interface. Amazon EC2 automatically selects the IPv6 addresses from the subnet range. You can’t use this option if specifying specific IPv6 addresses.

--ipv6-addresses (list)

One or more specific IPv6 addresses to be assigned to the network interface. You can’t use this option if you’re specifying a number of IPv6 addresses.

(string)

Syntax:

"string" "string" ...

--network-interface-id (string)

The ID of the network interface.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To assign specific IPv6 addresses to a network interface

This example assigns the specified IPv6 addresses to the specified network interface.

Command:

aws ec2 assign-ipv6-addresses --network-interface-id eni-38664473 --ipv6-addresses 2001:db8:1234:1a00:3304:8879:34cf:4071 2001:db8:1234:1a00:9691:9503:25ad:1761

Output:

{
  "AssignedIpv6Addresses": [
      "2001:db8:1234:1a00:3304:8879:34cf:4071",
      "2001:db8:1234:1a00:9691:9503:25ad:1761"
  ],
  "NetworkInterfaceId": "eni-38664473"
}

To assign IPv6 addresses that Amazon selects to a network interface

This example assigns two IPv6 addresses to the specified network interface. Amazon automatically assigns these IPv6 addresses from the available IPv6 addresses in the IPv6 CIDR block range of the subnet.

Command:

aws ec2 assign-ipv6-addresses --network-interface-id eni-38664473 --ipv6-address-count 2

Output:

{
  "AssignedIpv6Addresses": [
      "2001:db8:1234:1a00:3304:8879:34cf:4071",
      "2001:db8:1234:1a00:9691:9503:25ad:1761"
  ],
  "NetworkInterfaceId": "eni-38664473"
}

Output¶

AssignedIpv6Addresses -> (list)

The new IPv6 addresses assigned to the network interface. Existing IPv6 addresses that were assigned to the network interface before the request are not included.

(string)

NetworkInterfaceId -> (string)
