Using AutoNet

If the machine IPv4 address is not automatically assigned by the DHCP server, a temporary IP address starting with 169.254 and not used on the network can be automatically selected by the machine.

The IP address assigned by the DHCP server is given priority over that selected by AutoNet.
You can confirm the current IPv4 address on the configuration page.
When AutoNet is running, the NetBIOS name is not registered on the WINS server.
The machine cannot communicate with devices that do not have the AutoNet function. However, this machine can communicate with Macintosh computers running Mac OS X 10.2.3. or higher.
