Among other things: indentation. :-)

You never match anything with this class. You either need a "subclass"
to match you "substring(hardware, 1, 6)" or a specific mathch, e.g.
"match if substring(hardrware, 1, 6) = 1:2:3:4:5:6;".

Please don't mix allow and deny. It has been revisited many times
recently on this list.

Please don't place host statements in anything but global scope.

Fix these errors first, then see what it says. I assume the obvious
culprit -- that all leased are just used -- has already been considered.
