Subnet mask
2
Subnet masks restrict network communication.
Example: PC1 can talk to PC2
• PC1
IP Address:
192.168.1.2
Subnet Mask:
255.255.255.0
• PC2
IP Address:
192.168.1.3
Subnet Mask:
255.255.255.0
Note
0 denotes that there is no limit to communication at this part of the address.
In the above example, we can communicate with anything that has an IP address that begins with
192.168.1.X
.
Gateway (and router)
2
A gateway is a network point that acts as an entrance to another network and sends data transmitted via the
network to an exact destination. The router knows where to direct data that arrives at the gateway. If a
destination is located at an external network, the router transmits data to the external network. If your network
communicates with other networks, you may need to configure the Gateway IP address. If you do not know
the Gateway IP address then contact your Network Administrator.
