Netmask:
This is a value which when expanded into binary provides a mapping to define
which portions of IP address groups can be classified as host devices and network
devices. Netmask defines the address space of the network segment where device
resides. 255.255.255.0 (or /24) Netmask is commonly used among many C Class IP
networks.
Gateway IP:
Typically, this is the IP address of the host router which provides the point of
connection to the internet. This can be a DSL modem, Cable modem, or a WISP gateway
router. Device will direct the packets of data to the gateway if the destination host is not
within the local network. Gateway IP address should be from same address space (on
same network segment) as the device.
Primary/Secondary DNS IP:
The Domain Name System (DNS) is an internet "phone book" which translates domain
names to IP addresses. These fields identify the server IP addresses of where the device
looks for the translation source.
Primary DNS server IP address
should be specified for the device management purposes.
Secondary DNS
server IP address is optional. It is used as the fail-over in case the
primary DNS server will become unresponsive.
