Static IP Parameters
If DHCP is not available, you must provide the serial device server with
several important network parameters. These parameters are listed below.
•
IP address
—The unique, computer-readable address of a device on
your network. An IP address typically is represented as four decimal
numbers separated by periods (for example,
130.164.54.200)
.
•
Subnet mask
—A code that helps the network device determine
whether another device is on the same network or a different network.
•
Gateway IP
—The IP address of a device that acts as a gateway, which
is a connection between two networks. If your network does not have
a gateway, set this parameter to
0.0.0.0
.
•
DNS Server
—The IP address of a network device that stores
hostnames and translates them into IP addresses. If your network does
not have a DNS server, set this parameter to
0.0.0.0
.
Choosing a Static IP Address
For a Network Administered by a Network
Administrator
If you are adding the serial device server to an existing Ethernet network,
you must choose IP addresses carefully. Contact your network
administrator to obtain an appropriate static IP address for your serial
device server. Also, have the network administrator assign the proper
subnet mask, gateway, and DNS server addresses.
For a Network without a Network Administrator
If you are assembling your own small Ethernet network, you can choose
your own IP addresses. The subnet mask determines the IP address
format. You should use the same subnet mask as the computer you are
using to configure your serial device server. If your subnet mask is
255.255.255.0
, the first three numbers in every IP address on the
