Quickly identify abandoned static and DHCP reserved IP addresses within IP Address Manager (IPAM).
Easily reclaim IP addresses by editing configuration properties, including DHCP reservation settings within IPAM.
Monitor DHCP scopes from IPAM’s dashboard and receive alerts when they exceed utilization thresholds.
To find abandoned addresses, select a subnet to examine. Next, examine each address record and pay close attention to the Last Response column. Look for addresses associated with devices that have not been observed on the network for an extended period of time—for example, 30+ days. Then look at the status. You will probably want to reclaim addresses that have a status of “Used” and have not observed for an extended period of time. If the DHCP Reservation attribute is set to “YES,” then you also know this address has been reserved in a DHCP scope.
Once you have identified an abandoned address, select it and edit its configuration properties. To reclaim the address, change its status from Used to Available. If the address has been reserved in DHCP, simply uncheck DHCP Reservation. That’s all there is to reclaiming unused IP addresses.
Finally, to help ensure that your sublets and scopes never run low on available addresses, you can monitor them and receive alerts when they exceed utilization thresholds. This allows you to proactively examine the subnet or scope and find unused addresses to reclaim.
IP Address Manager
Do away with IP tracking spreadsheets and actively identify and manage IPv4 and IPv6 addresses.
Use an affordable and fully integrated DHCP, DNS, and IP address management software to administer your environment.
Stay on top of IP address conflicts, subnets/scope depletion, or mismatched DNS entries.
