I had this issue yesterday on 17.10. The IPV4 address for my Ethernet interface vanished. I could not find any option in the network portion of settings to ask the DHCP for the IP address, and sudo service network-manager restart did not recover, so I rebooted the system. This is obviously an extremely rare situation and I do not know how to reproduce it. If there is no notification that the network manager can register for to detect this situation automatically then there should be a reinitialize button in the network settings GUI.
