AWS v7.10.0 published on Friday, Oct 24, 2025 by Pulumi
pulumi/pulumi-aws

    Provides an VPC subnet resource.

    NOTE: Due to AWS Lambda improved VPC networking changes that began deploying in September 2019, subnets associated with Lambda Functions can take up to 45 minutes to successfully delete. To allow for successful deletion, the provider will wait for at least 45 minutes even if a shorter delete timeout is specified.

    Example Usage

    Basic Usage

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const main = new aws.ec2.Subnet("main", {
    vpcId: mainAwsVpc.id,
    cidrBlock: "10.0.1.0/24",
    tags: {
        Name: "Main",
    },
});

    import pulumi

    Subnets In Secondary VPC CIDR Blocks

    When managing subnets in one of a VPC’s secondary CIDR blocks created using a aws.ec2.VpcIpv4CidrBlockAssociation resource, it is recommended to reference that resource’s vpc_id attribute to ensure correct dependency ordering.

    Subnet Resource Properties

    To learn more about resource properties and how to use them, see Inputs and Outputs in the Architecture and Concepts docs.

    Inputs

    In Python, inputs that are objects can be passed either as argument classes or as dictionary literals.

    The Subnet resource accepts the following input properties:

    VpcId string
    The VPC ID.
    AssignIpv6AddressOnCreation bool
    Specify true to indicate that network interfaces created in the specified subnet should be assigned an IPv6 address. Default is false
    AvailabilityZone string
    AZ for the subnet.
    AvailabilityZoneId string
    AZ ID of the subnet. This argument is not supported in all regions or partitions. If necessary, use availability_zone instead.
    CidrBlock string
    The IPv4 CIDR block for the subnet.
    CustomerOwnedIpv4Pool string
    The customer owned IPv4 address pool. Typically used with the map_customer_owned_ip_on_launch argument. The outpost_arn argument must be specified when configured.
    EnableDns64 bool
    Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations. Default: false.
    EnableLniAtDeviceIndex int
    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).
    EnableResourceNameDnsARecordOnLaunch bool
    Indicates whether to respond to DNS queries for instance hostnames with DNS A records. Default: false.
    EnableResourceNameDnsAaaaRecordOnLaunch bool
    Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records. Default: false.
    Ipv6CidrBlock string
    The IPv6 network range for the subnet, in CIDR notation. The subnet size must use a /64 prefix length.
    Ipv6Native bool
    Indicates whether to create an IPv6-only subnet. Default: false.
    MapCustomerOwnedIpOnLaunch bool
    Specify true to indicate that network interfaces created in the subnet should be assigned a customer owned IP address. The customer_owned_ipv4_pool and outpost_arn arguments must be specified when set to true. Default is false.
    MapPublicIpOnLaunch bool
    Specify true to indicate that instances launched into the subnet should be assigned a public IP address. Default is false.
    OutpostArn string
    The Amazon Resource Name (ARN) of the Outpost.
    PrivateDnsHostnameTypeOnLaunch string
    The type of hostnames to assign to instances in the subnet at launch. For IPv6-only subnets, an instance DNS name must be based on the instance ID. For dual-stack and IPv4-only subnets, you can specify whether DNS names use the instance IPv4 address or the instance ID. Valid values: ip-name, resource-name.
    Region string
    Region where this resource will be managed. Defaults to the Region set in the provider configuration.
    Tags Dictionary<string, string>
    A map of tags to assign to the resource. .If configured with a provider default_tags configuration block present, tags with matching keys will overwrite those defined at the provider-level.
    VpcId string
    The VPC ID.
    AssignIpv6AddressOnCreation bool
    Specify true to indicate that network interfaces created in the specified subnet should be assigned an IPv6 address. Default is false
    AvailabilityZone string

    Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records. Default: false.
    Ipv6CidrBlock string
    The IPv6 network range for the subnet, in CIDR notation. The subnet size must use a /64 prefix length.
    Ipv6Native bool
    Indicates whether to create an IPv6-only subnet. Default: false.
    MapCustomerOwnedIpOnLaunch bool
    Specify true to indicate that network interfaces created in the subnet should be assigned a customer owned IP address. The customer_owned_ipv4_pool and outpost_arn arguments must be specified when set to true. Default is false.
    MapPublicIpOnLaunch bool
    Specify true to indicate that instances launched into the subnet should be assigned a public IP address. Default is false.
    OutpostArn string
    The Amazon Resource Name (ARN) of the Outpost.
    PrivateDnsHostnameTypeOnLaunch string
    The type of hostnames to assign to instances in the subnet at launch. For IPv6-only subnets, an instance DNS name must be based on the instance ID. For dual-stack and IPv4-only subnets, you can specify whether DNS names use the instance IPv4 address or the instance ID. Valid values: ip-name, resource-name.
    Region string
    Region where this resource will be managed. Defaults to the Region set in the provider configuration.
    Tags map[string]string
    A map of tags to assign to the resource. .If configured with a provider default_tags configuration block present, tags with matching keys will overwrite those defined at the provider-level.
    vpcId String
    The VPC ID.
    assignIpv6AddressOnCreation Boolean
    Specify true to indicate that network interfaces created in the specified subnet should be assigned an IPv6 address. Default is false

    cidrBlock String
    The IPv4 CIDR block for the subnet.
    customerOwnedIpv4Pool String
    The customer owned IPv4 address pool. Typically used with the map_customer_owned_ip_on_launch argument. The outpost_arn argument must be specified when configured.
    enableDns64 Boolean
    Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations. Default: false.
    enableLniAtDeviceIndex Number
    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).
    enableResourceNameDnsARecordOnLaunch Boolean
    Indicates whether to respond to DNS queries for instance hostnames with DNS A records. Default: false.
    enableResourceNameDnsAaaaRecordOnLaunch Boolean
    Indicates whether to respond to DNS queries for instance hostnames with DNS AAAA records. Default: false.
    ipv6CidrBlock String
    The IPv6 network range for the subnet, in CIDR notation. The subnet size must use a /64 prefix length.
    ipv6CidrBlockAssociationId String
    The association ID for the IPv6 CIDR block.
    ipv6Native Boolean
    Indicates whether to create an IPv6-only subnet. Default: false.
    mapCustomerOwnedIpOnLaunch Boolean
    Specify true to indicate that network interfaces created in the subnet should be assigned a customer owned IP address. The customer_owned_ipv4_pool and outpost_arn arguments must be specified when set to true. Default is false.
