IP Address Utilization
The IP address utilization displays the usage details for IP addresses in a subnet or a pool:
- Percentage Utilization: The IP addresses that are in use as a percentage of the total IP addresses available in the subnet or pool.
This value is equal to (Utilized IP Addresses
/ Total IP Addresses ) * 100.
- Total IP Addresses: The total number of IP addresses available in the subnet or pool, including the subnet or pool start and end addresses.
- Utilized IP Addresses: The number of IP addresses that are currently
assigned to static hosts and dynamic hosts from the subnet. Or, for a pool, the number of IP addresses that are currently
assigned to dynamic hosts.
- Available IP Addresses: The total number of IP addresses that are
currently available for assignment in the network.
This value is equal to (Total IP Addresses
- Utilized IP Addresses).

* Show only subnets with percentage utilization less than
When the option is selected and a value is configured, only those subnets
whose percentage utilization is more than or less than the configured value
are displayed.
- Click Show Utilization.
The IP address utilization details of the selected subnets are displayed.
You must wait for the complete details of all subnets to be loaded into the
table. The status bar displays Done when the complete
