Subnet mask is made for the purpose to get more network
address because any IP device in a network must own its
IP address, composed of Network address and Host
address, otherwise can't communicate with other devices
each other. But unfortunately, the network classes A, B,
and C are all too large to fit for almost all networks,
hence, subnet mask is introduced to solve this problem.
Subnet mask uses some bits from host address and makes
an IP address looked Network address, Subnet mask
number and host address. It is shown in the following
figure. This reduces the total IP number of a network able
to support, by the amount of 2 power of the bit number of
subnet number (2^(bit number of subnet number))
Subnet mask is used to set the subnet mask value, which
should be the same value as that of the other devices
resided in the same network it attaches.
For more information, please also see the Section 2-1-4
"IP Address Assignment" in this manual.
Default: 255.255.255.0
Set an IP address for a gateway to handle those packets
that do not meet the routing rules predefined in the
device. If a packet does not meet the criteria for other
pre-defined path, it must be forwarded to a default router
on a default path. This means any packet with undefined
IP address in the routing table will be sent to this device
unconditionally.
