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.
For more information, please also see the Section 2-1-5 “IP Address Assignment” in
this manual.
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
