%common;]> The tenant ID in a multi-tenancy cloud. The UUID for the subnet of interest to you. Lists subnets to which the specified tenant has access. Default policy settings returns exclusively subnets owned by the tenant submitting the request, unless the request is submitted by an user with administrative rights. You can control which attributes are returned by using the fields query parameter. You can filter results by using query string parameters. For information, see Filtering and Column Selection in the OpenStack Networking API v2.0 Reference. &fault401; Creates a subnet on a specified network. By default, OpenStack Networking creates IP v4 subnets. To create an IP v6 subnet, you must specify the value 6 for the ip_version attribute in the request body. OpenStack Networking does not try to derive the correct IP version from the provided CIDR. If the parameter for the gateway address, gateway_ip, is not specified, OpenStack Networking allocates an address from the cidr for the gateway for the subnet. To specify a subnet without a gateway, specify the value null for the gateway_ip attribute in the request body. If allocation pools attribute, allocation_pools, is not specified, OpenStack Networking automatically allocates pools for covering all IP addresses in the CIDR, excluding the address reserved for the subnet gateway. Otherwise, you can explicitly specify allocation pools as shown in the following example. When allocation_pools and gateway_ip are both specified, it is up to the user to ensure that the gateway IP does not overlap with the specified allocation pools; otherwise a 409 Conflict error occurs. &subnetCreateParameters; &subnetListParameters; &fault400; &fault401; &fault403; &fault404; &fault409conflict; Creates multiple subnets in a single request. Specify a list of subnets in the request body. The bulk create operation is always atomic. Either all or no subnets in the request body are created. &subnetCreateParameters; &subnetListParameters; &fault400; &fault401; &fault403; &fault404; &fault409conflict; Shows information for a specified subnet. You can control which attributes are returned by using the fields query parameter. For information, see Filtering and Column Selection in the OpenStack Networking API v2.0 Reference. &subnetListParameters; &fault401; &fault404; Updates a specified subnet. Some attributes, such as IP version (ip_version), CIDR (cidr), and IP allocation pools (allocation_pools) cannot be updated. Attempting to update these attributes results in a 400 Bad Request error. &subnetCreateParameters; &subnetListParameters; &fault400; &fault401; &fault403; &fault404; Deletes a specified subnet. The operation fails if subnet IP addresses are still allocated. &fault401; &fault404; &fault409conflict;
