All Implemented Interfaces:

DryRunSupportedRequest<CreateSubnetRequest>, java.io.Serializable, java.lang.Cloneable

public class CreateSubnetRequest
extends AmazonWebServiceRequest
implements java.io.Serializable, DryRunSupportedRequest<CreateSubnetRequest>

Container for the parameters to the CreateSubnet operation.

Creates a subnet in an existing VPC.

When you create each subnet, you provide the VPC ID and the CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you want only a single subnet in the VPC), or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).

IMPORTANT: AWS reserves both the first four and the last IP address in each subnet's CIDR block. They're not available for use.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

If you launch an instance in a VPC using an Amazon EBS-backed AMI, the IP address doesn't change if you stop and restart the instance (unlike a similar instance launched outside a VPC, which gets a new IP address when restarted). It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.

For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide .

Constructor Detail

CreateSubnetRequest

public CreateSubnetRequest()

Default constructor for a new CreateSubnetRequest object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.

CreateSubnetRequest

public CreateSubnetRequest(java.lang.String vpcId,
                           java.lang.String cidrBlock)

Constructs a new CreateSubnetRequest object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

vpcId - The ID of the VPC.

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Method Detail

getVpcId

public java.lang.String getVpcId()

The ID of the VPC.

Returns:

The ID of the VPC.

setVpcId

public void setVpcId(java.lang.String vpcId)

The ID of the VPC.

Parameters:

vpcId - The ID of the VPC.

withVpcId

public CreateSubnetRequest withVpcId(java.lang.String vpcId)

The ID of the VPC.

Returns a reference to this object so that method calls can be chained together.

Parameters:

vpcId - The ID of the VPC.

Returns:

A reference to this updated object so that method calls can be chained together.

getCidrBlock

public java.lang.String getCidrBlock()

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns:

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

setCidrBlock

public void setCidrBlock(java.lang.String cidrBlock)

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Parameters:

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

withCidrBlock

public CreateSubnetRequest withCidrBlock(java.lang.String cidrBlock)

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns a reference to this object so that method calls can be chained together.

Parameters:

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns:

A reference to this updated object so that method calls can be chained together.

getAvailabilityZone

public java.lang.String getAvailabilityZone()

The Availability Zone for the subnet.

Default: AWS selects one for you. If you create more than one subnet in your VPC, we may not necessarily select a different zone for each subnet.

Returns:

The Availability Zone for the subnet.

Default: AWS selects one for you. If you create more than one subnet in your VPC, we may not necessarily select a different zone for each subnet.

setAvailabilityZone

public void setAvailabilityZone(java.lang.String availabilityZone)

The Availability Zone for the subnet.

Default: AWS selects one for you. If you create more than one subnet in your VPC, we may not necessarily select a different zone for each subnet.

Parameters:

availabilityZone - The Availability Zone for the subnet.

Default: AWS selects one for you. If you create more than one subnet in your VPC, we may not necessarily select a different zone for each subnet.

withAvailabilityZone

public CreateSubnetRequest withAvailabilityZone(java.lang.String availabilityZone)

The Availability Zone for the subnet.

Default: AWS selects one for you. If you create more than one subnet in your VPC, we may not necessarily select a different zone for each subnet.

Returns a reference to this object so that method calls can be chained together.
