Subnet Mask
A pattern of bits in IP address format (e.g., 255.255.255.0) which, when bitwise
"and"ed with your address, produces a network address. If an outgoing packet's
network address has the same network address as the source of the packet, it is sent
on the local network wire, to be received by a device on that local network.
Otherwise, it is sent to the gateway address instead, to be routed to a device existing
on another network.
