I think that was/is inherited from dns/bind, at least no network name can 
begin with a number, which I found did not work for a hostname on my 
local network even using hosts files. The machine it runs is sold as a 
6040 milling machine but I had to name it sixty40 before I could make it 
network.

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.

Cheers, Gene Heskett.
