Let's peel this issue back to the basics.  

This does *not* have 254 IP addresses on that interface.  The
interface still has only one address on that interface.  There are 254
other addresses on the subnet, but only one of them belongs to your
machine.  If you want the machine to answer to 127.0.0.2, you still
need to add it separately.
