Type:
Specify the address type and enter the corresponding information.
-
Host:
Defines a single host by its IP address. The netmask for a Host
address object will automatically be set to 32-bit (255.255.255.255) to
identify it as a single host. If you choose Host, enter the IP address of the
host in the
IP Address
field.
-
Range:
Defines a range of contiguous IP addresses. No netmask is
associated with the Range address object, but internal logic generally
treats each member of the specified range as a 32-bit masked host
object. If you choose Range, enter the starting IP address in the
Starting
IP Address
field and the ending IP address in the
Ending IP Address
field.
-
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.
