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 the 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. The 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.

The NPort plays the role of DNS client. Functions that support domain name in the NPort are Time Sever IP Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and IP Location Server.

SNMP Settings

Community Name

Setting	Factory Default	Necessity
1 to 39 characters	public	Optional
(E.g., Support, 886-89191230 #300)

A community name is a plain-text password mechanism that is used to weakly authenticate queries to agents of managed network devices.

Contact

Setting	Factory Default	Necessity
1 to 39 characters	None	Optional
(E.g., Support, 886-89191230 #300)

The SNMP contact information usually includes an emergency contact name and telephone or pager number.

Location

Setting	Factory Default	Necessity
1 to 39 characters	None	Optional
(E.g., Floor 1, office 2)

Specify the location string for SNMP agents such as NPort. This string is usually set to the street address where the NPort is physically located.

IP Address Report

When device servers in the NPort 5000 line are used in a dynamic IP environment, users must spend more time with IP management tasks. For example, the NPort works as a server (TCP or UDP), and the host, which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to the server, the host must take care of what happens when the IP changes.

Device servers in the NPort 5000 line help out by periodically reporting their IP address to the IP location server, in case the dynamic IP has changed. The parameters shown below are used to
