Subnet Mask; Gateway (And Router) - Brother MFC-255CW Network Manual

Configuring your machine for a network with an Ethernet cable connection (Not available for MFC-253CW, MFC-255CW and

How the IP address is assigned to your print server:

address from that server.
Note
On smaller networks, the DHCP server may be the Router.
For more information on DHCP, BOOTP and RARP, see Using DHCP to configure the IP address
on page 137, Using BOOTP to configure the IP address on page 138 and Using RARP to configure the IP
address on page 139.
If you do not have a DHCP/BOOTP/RARP server, the Automatic Private IP Addressing (APIPA) protocol will
automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255. For more
information on APIPA, see Using APIPA to configure the IP address on page 139.

Subnet mask

Subnet masks restrict network communication.
Example: Computer1 can talk to Computer2
• Computer1
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
• Computer2
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 any device that has an IP address that begins with
192.168.1.X.

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 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.
