Querying Subnet Pools¶

Function¶

This API is used to query subnet pools. Pagination query is supported.

URI¶

GET /v2.0/subnetpools

Example:

GET https://{Endpoint}/v2.0/subnetpools?fields=id&fields=name&fields=prefixes&fields=default_prefixlen&fields=address_scope_id&fields=is_default

Example of querying subnet pools by page

GET https://{Endpoint}/v2.0/subnetpools?limit=2&marker=03f761e6-eee0-43fc-a921-8acf64c14988&page_reverse=False

Request Message¶

None

Response Message¶

**Table 1** Response parameter¶
Parameter	Type	Description
subnetpools	Array of subnetpool objects	Specifies the subnet pool list. For details, see Table 2.
subnetpools_links	Array of SubnetpoolsLink objects	Shows pagination information about subnet pools. Only when limit is used for filtering and the number of resources exceeds the value of limit or 2000 (default value of limit), value next will be returned for rel and a link for href.

**Table 2** **subnetpool** objects¶
Attribute	Type	Description
id	String	Specifies the subnet pool ID. This parameter is not mandatory when you query subnet pools.
name	String	Specifies the subnet pool name.
ip_version	Integer	Specifies the IP address version. The value can be 4 (IPv4) or 6 (IPv6).
default_quota	Integer	Specifies the upper limit of the prefix space that can be allocated from the subnet pool to the subnet. For IPv4 subnet pools, default_quota is measured in units of /32. For IPv6 subnet pools, default_quota is measured in units of /64.
project_id	String	Specifies the project ID.
created_at	String	Specifies the time (UTC) when the subnet pool is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the subnet pool rule is updated. Format: yyyy-MM-ddTHH:mm:ss
prefixes	Array of strings	Specifies a list of subnet prefixes that are assigned to the subnet pool. The adjacent prefixes are merged and treated as a single prefix. Each subnet prefix must be unique.
min_prefixlen	Integer	Specifies the minimum number for the prefix of a subnet that can be allocated from the subnet pool. The minimum number for the prefix of an IPv4 subnet is 8, and that of an IPv6 subnet is 64.
address_scope_id	String	Specifies the ID of the address range allocated to the subnet pool. Only the administrator can specify this attribute.
shared	Boolean	Specifies whether the network can be shared to all projects.
tenant_id	String	Specifies the project ID.
default_prefixlen	Integer	Specifies the default prefix to be allocated to a subnet if the cidr or prefixlen is not specified when you create the subnet. The default value is 8 for an IPv4 subnet and 64 for an IPv6 subnet.
max_prefixlen	Integer	Specifies the maximum number for the prefix of a subnet that can be allocated from the subnet pool. The maximum number for the prefix of an IPv4 subnet is 32, and that of an IPv6 subnet is 128.
description	String	Provides supplementary information about the subnet pool.
is_default	Boolean	Specifies whether this is the default subnet pool.
tags	Array of strings	Specifies the tags.

**Table 3** **SubnetpoolsLink** objects¶
Parameter	Type	Description
href	String	Specifies the API link.
rel	String	Specifies the relationship between the API link and the API version.
