Current version have a "reserved" flag. If you set this on a lease, 
then the lease is bound permanently to that client and will not be 
re-assigned even if the lease is expired. In all other respects, the 
lease goes through the normal lifecycle and dynamic DNS works etc.

The downside is that there is no mechanism to set it other than 
stopping the server and editing the lease database.

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. 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 ...
