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)).
Network ID
32 bits
Host ID
Network ID
Host ID
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
