3-4. IP Configuration
IP configuration is one of the most important configurations in the switch. Without the proper setting, network manager will not be able to manage or view the device. The switch supports manual IP address setting. When IP address is changed, you must reboot the switch to have the setting taken effect and use the new IP to browse for web management.
Function name:

Parameter description:
IP Address:
Users can configure the IP settings and fill in new values. Then, click <Apply> button to update.
Default: 192.168.1.1 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)).
