Overview

This article provides brief information and steps to resolve the issue when the used IP Addresses Report reflects a higher number than what was used. 

Product section

IP Address Manager

Cause

The issue is caused when a device fails to respond to any SNMP or ICMP requests (this is for standard IPAM scanning not DHCP monitoring) for the period of time designated as the Transient Period. IPAM changes the status of the unresponsive IP address from Used to Available. IPAM continuously scans all managed IP addresses on your network. 

Resolution

Any associated custom attribute will be overwritten. You can assign Transient scan intervals on a per subnet basis from the Edit Subnet window. 

To configure Orion IPAM subnet scan settings:

  1. Click IP Addresses from the menu bar.
  2. Click IPAM Settings.
  3. Click Manage Subnet Scans Settings.
  4. Enter an appropriate value for the Transient Period.

Note: The Transient period must be a value from .2 to 340 days. 

If the above steps don't work check the IPAM node table and see if there are duplicate entries.
