D. Auto IP Report Protocol
The NPort Series provides several ways to configure Ethernet IP addresses. One of them is DHCP Client. When
you set up the NPort to use DHCP Client to configure Ethernet IP addresses, it will automatically send a DHCP
request over the Ethernet to find the DHCP Server. And then the DHCP Server will send an available IP address
to the NPort. The NPort will use this IP address for a period of time after receiving it. But the NPort will send a
DHCP request again to the DHCP Server. Once the DHCP Server realizes that this IP address is to be released
to another DHCP Client, the NPort then will receive a different IP address. For this reason, users sometimes find
that the NPort will use different IP addresses, not a fixed IP address.
In order to know what IP address the NPort is using, you need to set up parameters in Network Settings via the
Web browser. The figure below is the NPort Web console configuration window. Enter the IP address and the
Port number of the PC that you want to send this information to.
