ModifySubnetAttribute

Modifies a subnet attribute. You can only modify one attribute at a time.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

AssignIpv6AddressOnCreation

Specify true to indicate that network interfaces created in the specified subnet should be assigned an IPv6 address. This includes a network interface that's created when launching an instance into the subnet (the instance therefore receives an IPv6 address).

If you enable the IPv6 addressing feature for your subnet, your network interface or instance only receives an IPv6 address if it's created using version 2016-11-15 or later of the Amazon EC2 API.

Type: AttributeBooleanValue object

Required: No

CustomerOwnedIpv4Pool

The customer-owned IPv4 address pool associated with the subnet.

You must set this value when you specify true for MapCustomerOwnedIpOnLaunch.

Type: String

Required: No

MapCustomerOwnedIpOnLaunch

Specify true to indicate that network interfaces attached to instances created in the specified subnet should be assigned a customer-owned IPv4 address.

When this value is true, you must specify the customer-owned IP pool using CustomerOwnedIpv4Pool.

Type: AttributeBooleanValue object

Required: No

MapPublicIpOnLaunch

Specify true to indicate that network interfaces attached to instances created in the specified subnet should be assigned a public IPv4 address.

Type: AttributeBooleanValue object

Required: No

SubnetId

The ID of the subnet.

Type: String

Required: Yes

Response Elements

The following elements are returned by the service.

requestId

The ID of the request.

Type: String

return

Is true if the request succeeds, and an error otherwise.

Type: Boolean

Errors

For information about the errors that are common to all actions, see Common Client Errors.

Examples

Example 1

This example modifies the attribute for subnet-1a2b3c4d to specify that all instances launched into this subnet are assigned a public IPv4 address.

Sample Request


https://ec2.amazonaws.com/?Action=ModifySubnetAttribute
&SubnetId=subnet-1a2b3c4d
&MapPublicIpOnLaunch.Value=true
&AUTHPARAMS

Sample Response


<ModifySubnetAttributeResponse xmlns="http://ec2.amazonaws.com/doc/2016-11-15/">
    <requestId>c500a0bc-ad14-46c2-b9c5-e24aexample</requestId>
    <return>true</return>
</ModifySubnetAttributeResponse>

Example 2

This example modifies the attribute for subnet-1a2b3c4d to specify that all network interfaces created in this subnet (and therefore all instances launched into this subnet with a new network interface) are assigned an IPv6 address.
