How should I determine the way to assign an IP address to SX-ND4050G?

There are two ways to assign an IP address to SX-ND4050G; one is to Get IP address automatically from DHCP server and the other is to Assign IP address manually. Choose the way to assign an IP address according to your environment.

Solution You can use Get IP address automatically from DHCP server. As SX-ND4050G is set by default to Get IP address automatically, SX-ND4050G will obtain an IP address appropriate to your network environment from the DHCP server just by powering up SX-ND4050G.
Refer to Resetting to Factory Defaults for details on how to reset SX-ND4050G to the factory default settings.

Solution Please use DHCP Server feature of SX-ND4050G or Assign IP address manually. Keep in mind of the following points regarding the IP address to assign to SX-ND4050G.
  • Assign an IP address unique in the network.
  • Assign an IP address that has the same address class as the computer that will use SX-ND4050G.
    e.g. When an IP address of the computer is "192.168.0.xx", assign an address such as "192.168.0.100" that is not used by other network devices.
  • When the DHCP Server feature of SX-ND4050G is used, the IP address of SX-ND4050G is automatically set to "192.168.0.1".

(Tips about the IP address)

  • An IP address is a unique number for identifying network devices. An IP address is indicated with four numbers divided by a period (.), for example "192.168.0.1". The integer from 0-255 is used for each number.
  • An IP address is, depending on the number assigned, categorized to 3 classes below.
  • Numbers making up the IP address are either network numbers indicating network, or host numbers indicating each network device; each number indicates the different meaning based on the IP address class. Each class is categorized as the following diagram which is indicating a network number as n, and a host number as u. An IP address with the same network number must be assigned to the network devices in the same network segment.
  • There is an address range in the IP address called the private address that could be used freely. In the LAN environment not directly connected to the internet, an IP address is assigned within the range of the private address.

    First 1 digits in IP address Class Definition of IP address
    n: network number
    u: host number
    Size of the network to be used Private address
    0 - 127 A n.u.u.u Large network 10.0.0.0 - 10.255.255.255
    128 - 191 B n.n.u.u Mid-size network 172.16.0.0 - 172.31.255.255
    192 - 223 C n.n.n.u Small network 192.168.0.0 - 192.168.255.255
