As Justin Demaris says, it **should** not cause a 
problem - they are NOT broadcast or network 
addresses. The network address (note singular) is, the broadcast address (again, note 
singular) is That is basic level IP 
addressing stuff.

Addresses in between (eg are not 
broadcast addresses even if they end in 0 or 255.

However, there have been reports on this list in 
the past that some devices running bad code do 
"get it wrong" when presented with such an 
address/netmask - and if you have any such 
devices then you may want to exclude them from 
your pool (as others have described).

WANTED: "Software CD ROM Kit" for Canon CLBP 
360-PS printer (Canon part no RH6-3612, or 
possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the 
disk and re-install the printer OS on it.
This is NOT the same thing as the printer drivers 
to load on the computer - there's no problem 
If anyone knows where I might get hold of one I'd 
be grateful - requests to Canon drew a blank, 
it's been out of support for years.
Alternatively, if anyone has one of these and 
would let me image their hard disk ...
