No, I think this is incorrect.

It's a zeroconf route. The 169.254 network is used for devices like
mobile phones, handhelds, laptops etc. For example my SonyEriccson T610
always uses the same ip inside this block.

Have a look at http://www.zeroconf.org/

To turn of this behaviour use 

NOZEROCONF=yes

in /etc/sysconfig/network (for the whole network) or in
/etc/sysconfig/networking/devices/ifcfg-ethX (only one device)
