I recently added few devices to DFM. I am not doing auto-sync so whenever I add device from CS, I will have to manually add that particular device to DFM. Normally, once the device's IP is properly configure to the local host file, DFM resolves the IP to hostname. This time, DFM did not resolve. In DFM device import page, these devices are showing the hostname, however when these are imported, the IP addresses are the ones showing up.
I have tried to rediscover these devices in DFM, also deleted both from DFM and CS, reentered but still did not work.
