Gateway
Gateway When two computers on different net-
works want to communicate with each other,
the networks need to be connected with a
router. For example, surfing on the Internet
requires for packets to be routed from the Inter-
net to the network and vice versa. By using a
subnet mask, a computer can know whether
the receiver can be found on its network or
whether it is located outside of it. If it is located
outside the network, the computer will send a
packet to the router specified with the gateway
IP address.

with the TCP/IP protocol. A distinction is drawn
between private address spaces for local net-
works (intranet) and public addresses (Inter-
net).
