Subnet Mask
. The Subnet Mask (also known as the Network Mask) determines which portion of an IP
address is the network portion, and which portion is the host portion. Take, for example, a network in which
the Subnet Mask is 255.255.255.0. This determines (by using the values 255) that the first three numbers of a
network IP address identify this particular network, while the last digit (from 1 to 254) identifies the specific
host.
Gateway
. This IP address should be the IP address of the gateway device that allows for contact between the
Router and the remote network or host.
Hop Count
. This determines the maximum number of steps between network nodes that data packets will
travel. A node is any device on the network, such as PCs, print servers, routers, etc.
