I would always advise to have some form of nameresolution active, even if it is just the hosts file on the LMS server.
You can make LMS use the interface on a device that is returned when the name of the device requested from DNS.
For example if a device is known via CDP via a serial port LMS only knows that ip address of the serial interface. If a reverse namelookup gives you Router_A then a DNSlookup of ROUTER_A can provide the address of the loopback of the router on which you may wish to manage.
So maybe your hostfile is suficient but for larger networks DNS and reversenamelookup can help you to manage every device on the interface you wish to manage it
