Adding in a specific ip into an existing discovery profile, running discovery, the device is not discovered and the IP is now missing from the list of devices.
I created a test discovery profile, added the snmp profile and the single device, it discovered the device as expected. Deleted the device put it back in the regular ip domain discovery profile and it is not discovered and is removed from the list of ips after the discovery run.
When create pingable is disabled, and device is reachable but not manageable, it removes IP from the IP domain discovery profile
