Network Terms and Information
Subnet mask
Subnet masks restrict network communication.
 For example, Computer 1 can communicate with to Computer 2
• Computer 1
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
• Computer 2
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
The 0 in the Subnet mask signifies that there is no limit to communication at this part of the address. In the
example above this means that you can communicate with any device with an IP address that begins with
192.168.1.x. (where x is a number between 0 and 254).
Gateway (and router)
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 on 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 contact your network administrator.
