| So Reservations are used if you want to always assign the
same address/mac. Used for example printers, Servers, Etc.
An Exclusion is a range of addresses used for blocks of
addresses for example a pool of DHCP addresses that are
being assigned from a different source or static
IPaddresses. If you had all your servers say 192.168.1.2
to 192.168.1.10 I would use an exclusion. And if I had
two print servers say 192.168.1.11 and 192.168.1.12 I can
Reserve these using the MAC addresses of the device.
One last thing can you make a reservation on a different
subnet ? I notice a check box for Supported types
Both/DHCP or BootP. What is that for?
