IP address:
Users can configure the IP settings and fill in new values if users set the DHCP
function “Disable”. Then, click <Apply> button to update. When DHCP is
disabled, Default: 192.168.1.1
If DHCP is enabled, this field is filled by DHCP server and will not allow user
manually set it any more.
Subnet mask:
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. Default:
255.255.255.0
Default 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.
This means any packet with undefined IP address in the routing table will be sent
to this device unconditionally. Default: 192.168.1.254
