Your solution won't work. Besides being wrong for not
including/excluding required addresses, and wrong mask,
the problem that prevents your solution to work is that
none of router interfaces are covered by pool. That's
why you have to have pool 163.3.6.0 255.255.255.0 (it
will cover IP address of router interface, so that router
knows on what interface to run dhcp server). Then exclude
router interface's IP address and all other addresses
that are specified in requirements.
Hope this helps.
