How the IP address is assigned to your print server:
If you have a DHCP/BOOTP/RARP server in your network (typically a UNIX
®
Windows Vista
or Windows Server
from the DHCP server and register its name with any RFC 1001 and 1002-compliant dynamic name services.
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 125, Using BOOTP to configure the IP address on page 126 and Using RARP to configure
the IP address on page 127.
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 127.
If the APIPA protocol is disabled, the IP address of a Brother print server is 192.0.0.192. However, you can
easily change this IP address number to match with the IP address details of your network. For information
on how to change the IP address, see Setting the IP address and subnet mask on page 13.

Subnet mask

Subnet masks restrict network communication.
Example: Computer 1 can talk 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
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)

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 then contact your Network Administrator.
