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)
