Synopsis

Properties

CidrBlock	The IPv4 network range for the VPC, in CIDR notation.
EnableDnsHostnames	Indicates whether the instances launched in the VPC get DNS hostnames.
EnableDnsSupport	Indicates whether the DNS resolution is supported for the VPC.
InstanceTenancy	The allowed tenancy of instances launched into the VPC.
Ipv4IpamPoolId	The ID of an IPv4 IPAM pool you want to use for allocating this VPC's CIDR.
Ipv4NetmaskLength	The netmask length of the IPv4 CIDR you want to allocate to this VPC from an Amazon VPC IP Address Manager (IPAM) pool.
Tags	The tags for the VPC.

Properties

CidrBlock

The IPv4 network range for the VPC, in CIDR notation.

string? CidrBlock { get; }

Property Value

string

Remarks

For example, 10.0.0.0/16 . We modify the specified CIDR block to its canonical form; for example, if you specify 100.68.0.18/18 , we modify it to 100.68.0.0/18 .

You must specify either CidrBlock or Ipv4IpamPoolId .

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html#cfn-ec2-vpc-cidrblock

EnableDnsHostnames

Indicates whether the instances launched in the VPC get DNS hostnames.

object? EnableDnsHostnames { get; }

Property Value

object

Remarks

If enabled, instances in the VPC get DNS hostnames; otherwise, they do not. Disabled by default for nondefault VPCs. For more information, see DNS attributes in your VPC .

You can only enable DNS hostnames if you've enabled DNS support.

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html#cfn-ec2-vpc-enablednshostnames

Type union: either bool or IResolvable

EnableDnsSupport

Indicates whether the DNS resolution is supported for the VPC.

object? EnableDnsSupport { get; }

Property Value

object

Remarks

If enabled, queries to the Amazon provided DNS server at the 169.254.169.253 IP address, or the reserved IP address at the base of the VPC network range "plus two" succeed. If disabled, the Amazon provided DNS service in the VPC that resolves public DNS hostnames to IP addresses is not enabled. Enabled by default. For more information, see DNS attributes in your VPC .

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html#cfn-ec2-vpc-enablednssupport

Type union: either bool or IResolvable

InstanceTenancy

The allowed tenancy of instances launched into the VPC.

string? InstanceTenancy { get; }

Property Value

string

Remarks

Updating InstanceTenancy requires no replacement only if you are updating its value from dedicated to default . Updating InstanceTenancy from default to dedicated requires replacement.

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html#cfn-ec2-vpc-instancetenancy

Ipv4IpamPoolId

The ID of an IPv4 IPAM pool you want to use for allocating this VPC's CIDR.

string? Ipv4IpamPoolId { get; }

Property Value

string

Remarks

For more information, see What is IPAM? in the Amazon VPC IPAM User Guide .

You must specify either CidrBlock or Ipv4IpamPoolId .

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html#cfn-ec2-vpc-ipv4ipampoolid

Ipv4NetmaskLength

The netmask length of the IPv4 CIDR you want to allocate to this VPC from an Amazon VPC IP Address Manager (IPAM) pool.

double? Ipv4NetmaskLength { get; }

Property Value

double?

Remarks

For more information about IPAM, see What is IPAM? in the Amazon VPC IPAM User Guide .
