Description of response body (normal status)

Item Description
name The subnet name.
network_id The ID of the attached network.
tenant_id The ID of the project who owns the network.
dns_nameservers A list of DNS name servers for the subnet.

For example ["8.8.8.7", "8.8.8.8"].

The specified IP addresses are displayed in sorted order in ascending order.

The lowest IP address will be the primary DNS address.
allocation_pools The start and end addresses for the allocation pools.
host_routes A list of host route dictionaries for the subnet. For example:

"host_routes":[
	{
		"destination":"0.0.0.0/0",
		"nexthop":"172.16.1.254"
	},
	{
		"destination":"192.168.0.0/24",
		"nexthop":"192.168.0.1"
	}
]
gateway_ip The gateway IP address.
ip_version The IP version, which can be 4 or 6.
cidr The CIDR.
id The ID of the subnet.
enable_dhcp Set to "true" if DHCP is enabled, or "false" otherwise.
availability_zone The Availability Zone name.
ipv6_ra_mode This attribute is used to specify if the Networking service should transmit ICMPv6 packets, for a subnet.

This value is null.

ipv6_address_mode This attribute is used to control how addressing is handled by OpenStack. There are a number of different ways that guest instances can obtain an IPv6 address, and this attribute exposes these choices to users of the Networking API.

This value is null.
subnetpool_id The UUID of the subnet pool.

This value is null.
