-Network: Network address object like the Range object comprises
multiple hosts, but rather than being bound by specified upper and lower
range delimiters, the boundaries are defined by a valid netmask. Network
address objects must be defined by the network’s address and a
corresponding netmask. As a general rule, the first address in a network
(the network address) and the last address in a network (the broadcast
address) are unusable. If you choose Network, enter the subnet IP
address in the IP Address field and the broadcast address in the
Netmask field.
-MAC: Identifies a host by its hardware address or MAC (Media Access
Control) address. MAC addresses are uniquely assigned to wired or
wireless networking devices by their hardware manufacturers. MAC
addresses are 48-bit values that are expressed in 6 byte hex-notation. If
you choose MAC, enter the MAC address in the MAC field.
