Brother 5250DN ユーザーズマニュアル

Control panel setup

If the APIPA protocol is enabled, the print server will automatically allocate a Link-Local IP address in the 
range (169.254.1.0 - 169.254.254.255) when the print server cannot obtain an IP address through the IP 
METHOD you have set. 

By default, the APIPA protocol is enabled. You can disable the APIPA protocol using the BRAdmin 
Profesional utility and a web browser. For more information, see Changing the print server settings on page 
2-5.

You can also disable the APIPA protocol using the control panel on the top of the printer. Please follow these
