Description
This field is for the DNS server’s IP address, if applicable. With the DNS server configured,
the NPort device server can use domain names instead of IP addresses to access hosts.
Domain Name System (DNS) is how Internet domain names are identified and translated
into IP addresses. A domain name is an alphanumeric name, such as www.moxa.com, that
it is usually easier to remember than the numeric IP address. A DNS server is a host that
translates a text-based domain name into an IP address in order to establish a TCP/IP
connection. When the user wants to visit a particular website, the user’s computer sends
the domain name (e.g., www.moxa.com) to a DNS server to request that website’s
numeric IP address. When the IP address is received from the DNS server, the user’s
computer uses that information to connect to the website’s web server.
The NPort will play the role of a DNS client, actively querying the DNS server for the IP
address associated with a particular domain name.
