  Table 2 Response parameter

  Name	Type	Description
  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 is a string of 1 to 64 characters that can contain letters, digits, underscores (_), hyphens (-), and periods (.).
  description	String	Provides supplementary information about the subnet. The value is a string of 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. NOTE: This parameter is available only in the CN North-Beijing4 region and can be set only after the IPv6 OBT has been applied.
  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.
  extra_dhcp_opts	Array of extra_dhcp_opt objects	Specifies the NTP server address configured for the subnet. For details, see the extra_dhcp_opt object.

  Table 4 extra_dhcp_opt object

  Name	Mandatory	Type	Description
  opt_value	No	String	Specifies the NTP server address configured for the subnet. Constraints: The option ntp for opt_name indicates the NTP server configured for the subnet. Currently, only IPv4 addresses are supported. A maximum of four IP addresses can be configured, and each address must be unique. Multiple IP addresses must be separated using commas (,). The option null for opt_name indicates that no NTP server is configured for the subnet. The parameter value cannot be an empty string.
  opt_name	Yes	String	Specifies the NTP server address name configured for the subnet. Currently, the value can only be set to ntp.
