169.254.0.0/16 is the network address for LinkLocal autoconfigure
IP addresses. On Windows you are assigned an IP address out of this
network if you have set your adapter to DHCP but there´s no DHCP
server available. I havn´t seen this behavior on a Linux system, but
perhaps it´s implemented in some dhcp clients.

So, check that you´re not running a dhcp client.
