The DHCP console provides statistics concerning IPv4 and IPv6 address availability and usage. By default, these statistics are updated only when you start the DHCP console or when you select the server and then click the Refresh button on the toolbar.
If you monitor DHCP routinely, you might want these statistics to be updated automatically.
To do that, follow these steps: 1.
In the DHCP console, expand the node for the server you want to work with, right-click IPv4 or IPv6 as appropriate for the type of address you want to work with, and then click Properties.
On the General tab, select Automatically Update Statistics Every and enter an update interval in hours and minutes. Click OK.
