A ups can and often is, a network device addressable by the usual ipv4 local address, so if you want it to be resolved it must start with a alpha charactor. There is an rfc for that I'm sure but I can't quote it. My systems are all usb interfaces, and are happy with the default "myups" for a name, but aren't network accessible without going thru ssh first to get to the machine its actually plugged into.
