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.
