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
