Now I read the AI summary and got what I need:
It stores one row for each address in the hostNetwork table. Limits of this method The sleeping host must run fog-agent. The server uses the sleeping host’s own last report to find its subnet. A host with the legacy FOG Client, or with no client, has no rows, so the relay cannot help it. The old path still runs for it.So If I populate the hostNetwork table for the hosts that I need manually, It will work. Thank you for the details.
