View the history of DHCP leases handed out by the Managed Windows servers. You can view the DHCP lease history for a specific IPv4 network or for all networks within an IPv4 block.
The import process does not include DHCP leases. Leases are sent to Address Manager as part of the notification process. After the initial import from a Windows DHCP server, all existing leases are sent to Address Manager. Thereafter, leases are sent to Address Manager once per minute by default.
To view Windows DHCP lease history:
- Select the My IPAM tab. From the configuration drop-down menu, select a configuration.
- Select the IP Space tab. Tabs remember the page you last worked on, so select the IP Space tab again to ensure you are working with the Configuration information page.
Under IPv4 Blocks section, click an IPv4 block.
The Address Space tab for the IPv4 block opens.
Note: To view the DHCP lease history for a specific network, click an IPv4 network. On the network page, select the DHCP Leases History tab.
Select the DHCP Leases History tab. The DHCP
Leases History section opens.
The DHCP Leases History section displays the following information:
- Active IP Address—lists the IP addresses that are actively leased or that have a history of having been leased. The icon beside the address indicates the state of the address. For more information on IP address type icons, refer to Address types.
- Lease Time—displays the date and time the lease was granted.
- Expire Time—displays the date and time the lease is to expire.
- Number of Transactions—displays the number of transactions performed to assign, renew, or terminate the lease. The table is initially sorted in descending order, based on the number of transactions.
- State—displays the current state of the lease, such as DHCP Allocated, DHCP Free, or DHCP Reserved.
- Circuit ID—shows information specific to the circuit from which the request came.
- Name—the name you created for the IP address.
- Remote ID—shows information that identifies the relay agent.
- To view the details for an address, click an address in the Active IP Address column. To view the details for a server, click a server in the Primary Server or Secondary Server columns.
