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 BOOT METHOD you have set.

By default, the APIPA protocol is enabled. You can change the APIPA setting using the control panel of the printer or Web Based Management (web browser). When the APIPA protocol is disabled, the IP address doesn't change when the print server cannot obtain an IP address through the BOOT METHOD you have set. Therefore, the IP address of  a Brother print server is back to 192.0.0.192. 

To disable APIPA protocol, please follow one of the instructions below.

Using the Control Panel of the printer:

1. Make sure that the front cover is closed and the power cord is plugged in.
