ATTENTION
In Dynamic IP environments, the firmware will retry 3 times every 30 seconds until network
settings are assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1
second, to 3 seconds, to 5 seconds.
If the DHCP/BOOTP Server is unavailable, the firmware will use the default IP address
(192.168.127.254), Netmask, and Gateway for IP settings.

E.g., 192.168.1.1
(IP addresses of the form x.x.x.0 and
x.x.x.255 are invalid.)

When the user wants to visit a particular website, the computer asks a Domain Name System
(DNS) server for the website’s correct IP address, and the computer users the response to connect
to the web server. DNS is the way that Internet domain names are identified and translated into IP
addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easier to
remember. A DNS server is a host that translates this kind of text-based domain name into the
numeric IP address used to establish a TCP/IP connection.
In order to use NPort’s DNS feature, you need to set the IP address of the DNS server to be able to
access the host with the domain name. NPort provides DNS server 1 and DNS server 2
configuration items to configure the IP address of the DNS server. DNS Server 2 is included for
use when DNS sever 1 is unavailable.
NPort plays the role of DNS client. Functions that support domain name in NPort are Time Sever
IP Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and
IP Location Server.
