But unfortunately, the network classes A, B, and C are all too large to fit for almost

4. Web Management in SNMP-GSH2404L

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)).

32 bits

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.

Default: 255.255.255.0

Fallback Gateway:

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.
