If DHCP is selected (see above), a unique IP address will be
assigned to the Nano IP Series; if STATIC IP address mode has
been selected, enter a suitable value for the specific network.
Within any IP network,
each device must have its
own unique IP address.
For a small private network with IP addresses appearing similar to

subnet mask may be applicable.
If DHCP mode is selected, the DHCP server will populate this field.

In a very small network (e.g. point-to-point, and STATIC IP Address Mode),
the gateway value is not critical. The IP address of the most significant
device on the overall network may be entered, or, if only two Nano IP
Series units are being used, make the gateway of IP Series No. 1 = IP
address of IP Series No. 2; gateway of IP Series No. 2 = IP address of IP
Series No. 1. The idea behind this approach is: If an IP Series at ‗one end'
