Do you mean NOC imposed ?

Are these private addresses on a private network ? If so then you 
really ought to be going back to the NOC (or rather their management) 
and telling them to stop being a bunch of *****.

There really is no reason for imposing such constraints (and 
headaches) on a private network.

Conversely, there really should be any reason to require a printer to 
be on a public (IPv4) address.

OK, I see where you are - I've always preferred to keep printers on a 
static address because there is (or was) too much hassle having them 

As I say, you're in ground I don't cover so I'm a bit limited in what 
to suggest. I don't recall ever having problem like you describe 

There is another option that may be relevant, you'll have to look it 
up and work that out for yourself :
