Why not use something from the private ranges?

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

Also, Class A would let you address 16 million of these devices. Do you 
really have that many?

Also, quite a few large companies, universities, and service providers have 
hung onto their Class A address. What would happen if the users from the 
Internet that you mentioned below happened to be on the same Class A as you 
are using? IP spoofing protection (if you are using it) might not let these 
users in. Even if they got in, the responses to their packets might get 
routed internally not back to them. You could avoid these problems, of 
course, but why even risk having them?

I'm sure you have your reasons and you're just trolling for a sanity check. 
Without more details, we have to give you the sort of canned response that 
it's a bad idea. ;-)
