Auto IP Report Protocol
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 other 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 Web browser. The figure below is NPort Web console configuration window. Enter the IP
address and the Port number of the PC that you want to send this information to.
