IP configuration
Method
Static
DHCP
DHCP/BOOTP
BOOTP
AUTOIP
IP configuration is a required field. The default setting is Static.
ATTENTION
In Dynamic IP environments, the module will attempt to obtain an IP address from the DHCP or BOOTP server
3 times at 30-second intervals. The timeout for the first try will be 1 second, the second try will be 3 seconds,
and the last try will be 5 seconds.
If the DHCP/BOOTP Server is unavailable, the module will use the default IP address (192.168.127.254),
netmask, and gateway settings.
IP Address
Setting
E.g., 192.168.1.1
(IP addresses of the form x.x.x.0
and x.x.x.255 are invalid.)
An IP address is a number assigned to a network device, such as a computer, as a permanent address on the
network. Computers use the IP address to identify and talk to each other over the network. Choose a proper IP
address that is unique and valid in your network environment.
Netmask
Setting
E.g., 255.255.255.0
A subnet mask represents all the network hosts at one geographic location, in one building, or on the same
local area network. When a packet is sent out over the network, the module will use the subnet mask to check
whether the host specified in the packet is on a local network segment. If the address is on the same network
segment as the module, a connection is established directly from the module. Otherwise, the connection is
established through the default gateway.
Gateway
Setting
E.g., 192.168.1.1
A gateway acts as an entrance to another network. Usually, the computers that control traffic within the
network or at the local Internet service provider are gateway nodes. The module needs to know the IP address
of the default gateway computer in order to communicate with the hosts outside the local network environment.
For correct gateway IP address information, consult your network administrator.
DNS server 1 / DNS server 2
Setting
E.g., 192.168.1.1 (IP addresses of
the form x.x.x.0 and x.x.x.255 are
invalid)
The Domain Name System (DNS) is used to identify and translate Internet domain names into IP addresses. A
domain name is an alphanumeric name, such as moxa.com, that is usually easier to remember. A DNS server
is a host that translates the text-based domain name into the corresponding numeric IP address, which is used
