Response Parameters

**Table 2** Response parameter
Name	Type	Description
subnet	subnet object	Specifies the subnet objects.

**Table 3** **subnet** objects
Name	Type	Description
id	String	Specifies a resource ID in UUID format.
name	String	Specifies the subnet name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
description	String	Provides supplementary information about the subnet. The value can contain no more than 255 characters and cannot contain angle brackets (< or >).
cidr	String	Specifies the subnet CIDR block.
gateway_ip	String	Specifies the subnet gateway address.
ipv6_enable	Boolean	Specifies whether an IPv6 subnet can be created.
cidr_v6	String	Specifies the IPv6 subnet CIDR block. If the subnet is an IPv4 subnet, this parameter is not returned.
gateway_ip_v6	String	Specifies the IPv6 subnet gateway. If the subnet is an IPv4 subnet, this parameter is not returned.
dhcp_enable	Boolean	Specifies whether DHCP is enabled for the subnet.
primary_dns	String	Specifies the IP address of DNS server 1 on the subnet.
secondary_dns	String	Specifies the IP address of DNS server 2 on the subnet.
dnsList	Array of strings	Specifies the IP address list of DNS servers on the subnet.
availability_zone	String	Identifies the AZ to which the subnet belongs.
vpc_id	String	Specifies the ID of the VPC to which the subnet belongs.
status	String	Specifies the status of the subnet. The value can be ACTIVE, UNKNOWN, or ERROR. ACTIVE: indicates that the subnet has been associated with a VPC. UNKNOWN: indicates that the subnet has not been associated with a VPC. ERROR: indicates that the subnet is abnormal.
neutron_network_id	String	Specifies the ID of the corresponding network (OpenStack Neutron API).
neutron_subnet_id	String	Specifies the ID of the corresponding subnet (OpenStack Neutron API).
neutron_subnet_id_v6	String	Specifies the ID of the IPv6 subnet (OpenStack Neutron API). If the subnet is an IPv4 subnet, this parameter is not returned.
