[Dynamic] When unchecked, the unit is set for dynamic
(automatic) IP configuration by a
DHCP server
. A
DHCP server must be present on the network to use
this setting.
[Static]
When checked, the unit is set for static IP operation
using the
Static IP
,
Subnet
, and
Gateway
settings.
•
Static IP
Sets the
static IP address
of the unit. For private networks (i.e.
networks in which the IP addresses of its host devices are not
visible on the public Internet – as is almost always the case in
home, small office, and corporate networks),
RFC1918
defines a
range of IPv4 addresses that can be used:
Name
IP Address Range
24-bit block
10.0.0.0 – 10.255.255.255
20-bit block
172.16.0.0 – 172.31.255.255
16-bit block
192.168.0.0 – 192.168.255.255
•
Subnet
Sets the subnet mask of the unit. The
subnet mask
is used to
divide a larger network into smaller subnetworks. It is extremely
important to note that while devices can use any valid IP address
within the prescribed range, all devices placed on the same
subnet MUST use the same subnet mask. The largest subnet
masks corresponding to the private IP address ranges listed
above are as follows:
Name Subnet
Mask
24-bit block
255.0.0.0
20-bit block
255.240.0.0
16-bit block
255.255.0.0
•
Gateway
Sets the IP address of the network
gateway
. A gateway is a
network computer or device (like a router) that acts as a bridge to
another subnet within the same network, or an external network
(such as the Internet). In small networks where all devices
(including the DX navigator computer) are connected to the same
subnet, the
Gateway
setting can be left blank [0.0.0.0].
•
Dynamic IP
Displays the IP address currently assigned to the device by the
network DHCP server when set to [Dynamic] operation.
Small Network Setup Example
Network design and configuration depends greatly on how devices are meant to communicate
with each other as well as what devices are meant to be able to communicate. While the topic
of network setup and configuration is beyond the scope of this manual, this section illustrates
how to setup a small private network using static IP in the absence of a DHCP server. Such a
