Using APIPA to configure the IP address A
The Brother print server supports the Automatic Private IP Addressing (APIPA) protocol. With APIPA, clients
automatically configure an IP address and subnet mask when a DHCP server is not available. The device
chooses it's own IP address in the range 169.254.1.0 through to 169.254.254.255. The subnet mask is
automatically set to 255.255.0.0 and the gateway address is set to 0.0.0.0.
By default, the APIPA protocol is enabled. If you want to disable the APIPA protocol, you can disable it using
printer control panel. For more information, see Disabling the APIPA protocol on page 118.
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.
Using ARP to configure the IP address A
If you are unable to use the BRAdmin application and your network does not use a DHCP server, you can
also use the ARP command. The ARP command is available on Windows
®
systems that have TCP/IP
installed as well as UNIX
®
systems. To use arp enter the following command at the command prompt:
arp -s ipaddress ethernetaddress
ping ipaddress
Where ethernetaddress is the Ethernet address (MAC address) of the print server and ipaddress is the
IP address of the print server. For example:
Windows
®
systems A
Windows
®
systems require the dash “-” character between each digit of the Ethernet address.
arp -s 192.168.1.2 00-80-77-31-01-07
ping 192.168.1.2
UNIX
®
/Linux systems A
Typically, UNIX
®
and Linux systems require the colon “:” character between each digit of the Ethernet
address.
arp -s 192.168.1.2 00:80:77:31:01:07
ping 192.168.1.2
Note
You must be on the same Ethernet segment (that is, there cannot be a router between the print server and
operating system) to use the arp -s command.
If there is a router, you may use BOOTP or other methods described in this chapter to enter the IP address.
If your administrator has configured the system to deliver IP addresses using BOOTP, DHCP or RARP
your Brother print server can receive an IP address from any one of these IP address allocation systems.
In which case, you will not need to use the ARP command. The ARP command only works once. For
security reasons, once you have successfully configured the IP address of a Brother print server using the
ARP command, you cannot use the ARP command again to change the address. The print server will
ignore any attempts to do this. If you wish to change the IP address again, use Web Based Management
