# Subnets

## Create a subnet

This operation takes one parameter, an associative array, with the following keys:

Name | Description | Data type | Required? | Default value | Example value
--- | --- | --- | --- | --- | ---

`networkId`

Network this subnet is associated with

String

Yes

`eb60583c-57ea-41b9-8d5c-8fab2d22224c`

`ipVersion`

IP version

Integer (`4` or `6`)

Yes

`4`

`cidr`

CIDR representing the IP address range for this subnet

String (CIDR)

Yes

`192.168.199.0/25`

`name` | A human-readable name for the subnet. This name might not be unique. | String | No | `null` | `My subnet`
`gatewayIp` | IP address of the default gateway used by devices on this subnet | String (IP address) | No | First IP address in CIDR | `192.168.199.128`
`dnsNameservers` | DNS nameservers used by hosts in this subnet | Indexed array of strings | No | Empty array | `array('4.4.4.4', '8.8.8.8')`
`allocationPools` | Subranges of the CIDR available for dynamic allocation to ports | Indexed array of associative arrays | No | Every IP address in CIDR, excluding gateway IP address if configured | `array(array('start' => '192.168.199.2', 'end' => '192.168.199.127'))`
`hostRoutes` | Routes that should be used by devices with IP addresses from this subnet (not including the local subnet route) | Indexed array of associative arrays | No | Empty array | `array(array('destination' => '1.1.1.0/24', 'nexthop' => '192.168.19.20'))`
`enableDhcp` | Specifies whether DHCP is enabled for this subnet | Boolean | No | `true` | `false`
`tenantId` | Owner of the subnet. Only admin users can specify a tenant ID other than their own. | String | No | Same as tenant creating the subnet | `123456`

You can create a subnet as shown in the following example:

    /** @var $subnet OpenCloud\Networking\Resource\Subnet **/
    $subnet = $networkingService->createSubnet(array(
        'name' => 'My subnet',
        'networkId' => 'eb60583c-57ea-41b9-8d5c-8fab2d22224c',
        'ipVersion' => 4,
        'cidr' => '192.168.199.0/25'
    ));

## Create multiple subnets

This operation takes one parameter, an indexed array. Each element of this array must be an associative array with the keys shown in the preceding table.

You can create multiple subnets as shown in the following example:

    $subnets = $networkingService->createSubnets(array(
        array(
            'name' => 'My subnet #1'
        ),
        array(
            'name' => 'My subnet #2'
        )
    ));

    foreach ($subnets as $subnet) {
        /** @var $subnet OpenCloud\Networking\Resource\Subnet **/
    }

## List subnets

You can list all the subnets to which you have access as shown in the following example:

    $subnets = $networkingService->listSubnets();
    foreach ($subnets as $subnet) {
        /** @var $subnet OpenCloud\Networking\Resource\Subnet **/
    }

Get the executable PHP script for this example

## Get a subnet

You can retrieve a specific subnet by using that subnet’s ID, as shown in the following example:

    /** @var $subnet OpenCloud\Networking\Resource\Subnet **/
    $subnet = $networkingService->getSubnet('{subnetId}');

## Update a subnet

This operation takes one parameter, an associative array, with the following keys:

Name | Description | Data type | Required? | Default value | Example value
--- | --- | --- | --- | --- | ---
`name` | A human-readable name for the subnet. This name might not be unique. | String | No | `null` | `My updated subnet`
`gatewayIp` | IP address of the default gateway used by devices on this subnet | String (IP address) | No | First IP address in CIDR | `192.168.62.155`
`dnsNameservers` | DNS nameservers used by hosts in this subnet | Indexed array of strings | No | Empty array | `array('4.4.4.4', '8.8.8.8')`
`hostRoutes` | Routes that should be used by devices with IP adresses from this subnet (not including the local subnet route) | Indexed array of associative arrays | No | Empty array | `array(array('destination' => '1.1.1.0/24', 'nexthop' => '192.168.17.19'))`
`enableDhcp` | Specifies whether DHCP is enabled for this subnet | Boolean | No | `true` | `false`

You can update a subnet as shown in the following example:

    $subnet->update(array(
        'name' => 'My updated subnet',
        'hostRoutes' => array(
            array(
                'destination' => '1.1.1.0/24',
                'nexthop'     => '192.168.17.19'
            )
        ),
        'gatewayIp' => '192.168.62.155'
    ));

## Delete a subnet

You can delete a subnet as shown in the following example:

    $subnet->delete();
