How to manage duplicate IP addresses

Hello Teppo,

You can configure the default behavior in the System > Settings > Behavior page. For the Port Scan All IPs parameter, setting it to Disabled will set it to disabled by default in future discovery scans. However, this applies to port scans and does not actually discover the IP addresses. The setting you are looking for is Bypass Interface Inventory, which can only be disabled on a per device basis or by checking the checkbox in the Discovery Session before the devices are discovered. We do not have a global setting for this specific parameter. 

To delete the IP address from a device, in the Properties tab for the device when looking at the classic Device Properties, select the IP you want to delete under IP address and then click on the trash icon. Keep in mind that you cannot delete IPs associated with an interface.

As long as the duplicate IP is not the primary IP on multiple devices, there shouldn't be any issues and normally you should be able to ignore this entirely. What event are you getting that is referencing these duplicate IPs?
