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.

Important

  • 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.
