That is what reserving the numbers means. You do it based on the MAC
(ehternet) address of the device.

Now, excluding the addresses, on the other hand, is making sure the DHCP
service never touches them by making them off limits and giving the
devices STATIC IP addresses.
When you RESERVE the addresses, they are not static, they are just
reserved for that particular device and when the device requests an
address, it'll get the same one.
