I have quite a few workstations that do not have SNMP configured correctly or at all. For example, I have added the hostname to an IP address. As soon as IPAM scans that box the next time, it clears that as the box does not answer any SNMP. I want to poll the workstation looking to see if it is online or not, but don't want IPAM to remove info that I have entered. I have tried a few settings but nothing seems to work.
If you edit the IP then there should be an option you can remove to allow the scan to overwrite the data but it turns scanning off on the IP. That would be about the only option.
