Querying IP Address Usage on a Specified Network

Function

This API is used to query the IP address usage on a specified network.

The obtained information includes the total number of IP addresses on the network, the number of in-use IP addresses on the network, the total number of IP addresses on each subnet, and the number of in-use IP addresses on the subnet.

Notice

The first and the last two IP addresses on each subnet are reserved by the system for the gateway and DHCP service.
The total number of IP addresses and the number of in-use IP addresses described in this section and the subsequent sections do not include the IP addresses reserved by the system.
When assigning an IP address, you can specify the reserved IP address for the system. The reserved IP addresses will not be included in the number of in-use IP addresses and the total number of IP addresses no matter how the IP address is assigned.

URI

GET /v2.0/network-ip-availabilities/{network_id}

Table 1 describes the parameters.
