You should never see such an address >in public. Something is broken there. It is, however, quite valid and useful to address intermediary routers with numbers chosen from these private networks .. so long as their administrator can still reach them :-) It has the (significant) advantage of guaranteeing that no-one else can play with your gear. With address space being harder and harder to get, using private (sub)nets in this way can save you *lots* of numbers for hosts that really need global access, michael
