ec2_modify_subnet_attribute: Modifies a subnet attribute

Description

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

See https://www.paws-r-sdk.com/docs/ec2_modify_subnet_attribute/ for full documentation.

Usage

ec2_modify_subnet_attribute(
  AssignIpv6AddressOnCreation = NULL,
  MapPublicIpOnLaunch = NULL,
  SubnetId,
  MapCustomerOwnedIpOnLaunch = NULL,
  CustomerOwnedIpv4Pool = NULL,
  EnableDns64 = NULL,
  PrivateDnsHostnameTypeOnLaunch = NULL,
  EnableResourceNameDnsARecordOnLaunch = NULL,
  EnableResourceNameDnsAAAARecordOnLaunch = NULL,
  EnableLniAtDeviceIndex = NULL,
  DisableLniAtDeviceIndex = NULL
)

Arguments

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.

MapPublicIpOnLaunch

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

Amazon Web Services charges for all public IPv4 addresses, including public IPv4 addresses associated with running instances and Elastic IP addresses. For more information, see the Public IPv4 Address tab on the Amazon VPC pricing page.

SubnetId

[required] The ID of the subnet.

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.

CustomerOwnedIpv4Pool

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

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

EnableDns64

Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations.

You must first configure a NAT gateway in a public subnet (separate from the subnet containing the IPv6-only workloads). For example, the subnet containing the NAT gateway should have a 0.0.0.0/0 route pointing to the internet gateway. For more information, see Configure DNS64 and NAT64 in the Amazon VPC User Guide.

PrivateDnsHostnameTypeOnLaunch

The type of hostname to assign to instances in the subnet at launch. For IPv4-only and dual-stack (IPv4 and IPv6) subnets, an instance DNS name can be based on the instance IPv4 address (ip-name) or the instance ID (resource-name). For IPv6 only subnets, an instance DNS name must be based on the instance ID (resource-name).

EnableResourceNameDnsARecordOnLaunch

Indicates whether to respond to DNS queries for instance hostnames with DNS A records.

EnableResourceNameDnsAAAARecordOnLaunch

Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records.

EnableLniAtDeviceIndex

Indicates the device position for local network interfaces in this subnet. For example, 1 indicates local network interfaces in this subnet are the secondary network interface (eth1). A local network interface cannot be the primary network interface (eth0).

DisableLniAtDeviceIndex

Specify true to indicate that local network interfaces at the current position should be disabled.
